Target godep script change verifications
helps with #50319
`hack/verify-godeps.sh` takes ~15 minutes of the verify job time. We should not run it if not required, especially since the job is regularly timing out at 1 hour when this check is included.
https://github.com/kubernetes/kubernetes/pull/48653 added a check to run it if *anything* under `hack` was changed. This targetes just changes to the godep scripts

Alpha Dynamic Kubelet Configuration
Feature: https://github.com/kubernetes/features/issues/281
This proposal contains the alpha implementation of the Dynamic Kubelet Configuration feature proposed in ~#29459~ [community/contributors/design-proposals/dynamic-kubelet-configuration.md](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/dynamic-kubelet-configuration.md).
Please note:
- ~The proposal doc is not yet up to date with this implementation, there are some subtle differences and some more significant ones. I will update the proposal doc to match by tomorrow afternoon.~
- ~This obviously needs more tests. I plan to write several O(soon). Since it's alpha and feature-gated, I'm decoupling this review from the review of the tests.~ I've beefed up the unit tests, though there is still plenty of testing to be done.
- ~I'm temporarily holding off on updating the generated docs, api specs, etc, for the sake of my reviewers 😄~ these files now live in a separate commit; the first commit is the one to review.
/cc @dchen1107 @vishh @bgrant0607 @thockin @derekwaynecarr
```release-note
Adds (alpha feature) the ability to dynamically configure Kubelets by enabling the DynamicKubeletConfig feature gate, posting a ConfigMap to the API server, and setting the spec.configSource field on Node objects. See the proposal at https://github.com/kubernetes/community/blob/master/contributors/design-proposals/dynamic-kubelet-configuration.md for details.

[Federation] Make the hpa scale time window configurable
This PR is on top of open pr https://github.com/kubernetes/kubernetes/pull/45993.
Please review only the last commit in this PR.
This adds a config param to controller manager, the value of which gets passed to hpa adapter via sync controller.
This is needed to reduce the overall time limit of the hpa scaling window to much lesser (then the default 2 mins) to get e2e tests run faster. Please see the comment on the newly added parameter.
**Special notes for your reviewer**:
@kubernetes/sig-federation-pr-reviews
@quinton-hoole
@marun to please validate the mechanism used to pass a parameter from cmd line to adapter.
**Release note**:
```
federation-controller-manager gets a new flag --hpa-scale-forbidden-window.
This flag is used to configure the duration used by federation hpa controller to determine if it can move max and/or min replicas
around (or not), of a cluster local hpa object, by comparing current time with the last scaled time of that cluster local hpa.
Lower value will result in faster response to scalibility conditions achieved by cluster local hpas on local replicas, but too low
a value can result in thrashing. Higher values will result in slower response to scalibility conditions on local replicas.

- Extracted all OpenAPI specs to new repo `kube-openapi`
- Make OpenAPI spec aggregator to copy and rename any non-requal model (even with documentation change only).
- Load specs when adding APIServices and retry on failure until successful spec retrieval or a 404.
- Assumes all Specs except aggregator's Spec are static
- A re-register of any APIService will result in updating the spec for that service (Suggestion for TPR: they should be registered to aggregator API Server, Open for discussion if any more changes needed for another PR.)

**Special notes for your reviewer**:
We are splitting the PodPreset application logic in two phases. In first phase, we try to detect the conflicts in information merging without modifying the Pod at all. If conflict occurs, then we reject the PodPresets injection. Incase of no conflicts, we apply the PodPresets and merge the information.
**Release note**:
```release-note
PodPreset is not injected if conflict occurs while applying PodPresets to a Pod.
```
This introduces fake implementations of dynamic.Client and
dynamic.ClientPool. They function similarly to the fake generated
clientsets, since they're also based in testing.Fake.
Replaces use of --api-servers with --kubeconfig in Kubelet args across

Add a new API version apps/v1beta2
xref: #49135
This PR adds a new API version `apps/v1beta2` which contains a copy (of types, conversions, and defaults) of `apps/v1beta1` StatefulSet, Deployment, and their subresources. Note that `apps/v1beta2` is still WIP and we will make breaking changes to it before releasing 1.8.
Moving core controllers (StatefulSet, Deployment, ReplicaSet, DaemonSet) to `apps/v1beta2` is the first step of moving them to `apps/v1` (GA).
This PR is a starting point for DaemonSet and ReplicaSet to move from `/extensions` to `/apps` and for Deployment and StatefulSet to make some breaking changes (e.g. new defaults and/or remove deprecated fields).

Support customized system spec in the node conformance test and create the GKE system spec
ref: https://github.com/kubernetes/kubernetes/issues/46891
- System specs are located in `test/e2e_node/system/specs`. Created one for validating GKE images in `test/e2e_node/system/specs/gke.yaml`.
- `--image-spec-name` can be used to specify a system spec in node e2e and conformance tests. This option maps to `SYSTEM_SPEC_NAME` in a test properties file, which is the user facing configuration. So, users can specify `SYSTEM_SPEC_NAME=gke` to run the image validation using the GKE system spec.
- If `SYSTEM_SPEC_NAME` is unspecified, the default spec (`system.DefaultSysSpec`) will be used.
- We can also use `make test-e2e-node SYSTEM_SPEC_NAME=gke` to run tests using GKE image spec.

azure: msi: add managed identity field, logic
**What this PR does / why we need it**: Enables managed service identity support for the Azure cloudprovider. "Managed Service Identity" allows us to ask the Azure Compute infra to provision an identity for the VM. Users can then retrieve the identity and assign it RBAC permissions to talk to Azure ARM APIs for the purpose of the cloudprovider needs.
Per the commit text:
```
The azure cloudprovider will now use the Managed Service Identity
to retrieve access tokens for the Azure ARM APIs, rather than
requiring hard-coded, user-specified credentials.

Azure PD (Managed/Blob)
This is exactly the same code as this [PR](https://github.com/kubernetes/kubernetes/pull/41950). It has a clean set of generated items. We created a separate PR to accelerate the accept/merge the PR
CC @colemickens
CC @brendandburns
**What this PR does / why we need it**:
1. Adds K8S support for Azure Managed Disks.
2. Adds support for dedicated blob disks (1:1 to storage account) in addition to shared blob disks (n:1 to storage account).
3. Automatically manages the underlying storage accounts. New storage accounts are created at 50% utilization. Max is 100 disks, 60 disks per storage account.
2. Addresses the current issues with Blob Disks:
..* Significantly faster attach process. Disks are now usually available for pods on nodes under 30 sec if formatted, under a min if not formatted.
..* Adds support to move disks between nodes.
..* Adds consistent attach/detach behavior, checks if the disk is leased/attached on a different node before attempting to attach to target nodes.
..* Fixes a random hang behavior on Azure VMs during mount/format (for both blob + managed disks).
..* Fixes a potential conflict by avoiding the use of disk names for mount paths. The new plugin uses hashed disk uri for mount path.
The existing AzureDisk is used as is. Additional "kind" property was added allowing the user to decide if the pd will be shared, dedicated or managed (Azure Managed Disks are used).
Due to the change in mounting paths, existing PDs need to be recreated as PV or PVCs on the new plugin.

However, when it does run (e.g. https://k8s-gubernator.appspot.com/build/kubernetes-jenkins/pr-logs/pull/48630/pull-kubernetes-verify/38350/) it fails because the godep-save script now doesn't permit a compex GOPATH. verify-godeps.sh actually sets one because it restores godeps not using the `hack/godep-restore.sh` script.

Write reports for each upgrade test
Due to the way Ginkgo runs individual test cases and the level of coordination required for the upgrade tests, they were all run under a single Ginkgo test case. This PR generates and auxiliary report that break out the results of each upgrade test. This is accomplished by:
1) Wrapping `ginkgo.Fail` and `ginkgo.Skip` to get the actual failure or skip messages.
2) Recovering that info in the upgrade test to generate an auxiliary report.
I suggest reviewing commit by commit.

bazel: stamp multiple packages by using x_defs instead of linkstamp in go_binary rules
**What this PR does / why we need it**: Fixes regression introduced sometime in the last few months that prevented bazel-built clusters from identifying version properly.
It does so by updating the bazelbuild/rules_go and kubernetes/repo-infra dependencies to support using stamp values in `go_binary` `x_defs`, and then changing our `go_binary` rules to use `x_defs` instead of `linkstamp`.
This whole charade is necessary because we need to stamp version information in multiple packages.
This pretty much only affects the bazel build, so it should be low risk.

Add group alias names to API resources to allow discovery
**What this PR does / why we need it**:
Adds `GroupNames []string` to API resources, which represents the list of group aliases that every resource belongs to.
Partially fixes https://github.com/kubernetes/kubernetes/issues/41353
This moves the logic of "all" (which currently [translates](fbc94c0896/pkg/kubectl/cmd/util/shortcut_restmapper.go (L106)) to "pods,replicationcontrollers,services,...") to the server-side. Will allow clients like `kubectl` to discover group aliases instead of having it hardcoded and the API server to better handle consistency across multiple clients, version skew, etc; and will make "all" un-special and allow other groups to be created.
As a follow-up we'll patch `kubectl` to make groups aliases discoverable and the hardcoded list a fallback while we still have to support it.
Related to https://github.com/kubernetes/kubernetes/pull/42595#issuecomment-286839885.

Add configuration for encryption providers
## Additions
Allows providing a configuration file (using flag `--experimental-encryption-provider-config`) to use the existing AEAD transformer (with multiple keys) by composing mutable transformer, prefix transformer (for parsing providerId), another prefix transformer (for parsing keyId), and AES-GCM transformers (one for each key). Multiple providers can be configured using the configuration file.
Example configuration:
```
kind: EncryptionConfig
apiVersion: v1
resources:
- resources:
- namespaces
providers:
- aes:
keys:
- name: key1
secret: c2vjcmv0iglzihnly3vyzq==
- name: key2
secret: dghpcybpcybwyxnzd29yza==
- identity: {}
```
Need for configuration discussed in:
#41939
[Encryption](3418b4e4c6/contributors/design-proposals/encryption.md)
**Pathway of a read/write request**:
1. MutableTransformer
2. PrefixTransformer reads the provider-id, and passes the request further if that matches.
3. PrefixTransformer reads the key-id, and passes the request further if that matches.
4. GCMTransformer tries decrypting and authenticating the cipher text in case of reads. Similarly for writes.
## Caveats
1. To keep the command line parameter parsing independent of the individual transformer's configuration, we need to convert the configuration to an `interface{}` and manually parse it in the transformer. Suggestions on better ways to do this are welcome.
2. Flags `--encryption-provider` and `--encrypt-resource` (both mentioned in [this document](3418b4e4c6/contributors/design-proposals/encryption.md) ) are not supported in this because they do not allow more than one provider, and the current format for the configuration file possibly supersedes their functionality.
3. Currently, it can be tested by adding `--experimental-encryption-provider-config=config.yml` to `hack/local-up-cluster.sh` on line 511, and placing the above configuration in `config.yml` in the root project directory.

## TODO
1. Investigate if we need to store keys on disk (per [encryption.md](3418b4e4c6/contributors/design-proposals/encryption.md (option-1-simple-list-of-keys-on-disk)))
2. Look at [alpha flag conventions](https://github.com/kubernetes/kubernetes/blob/master/pkg/features/kube_features.go)
3. Need to reserve `k8s:enc` prefix formally for encrypted data. Else find a better way to detect transformed data.

Add initializer support to admission and uninitialized filtering to rest storage
Initializers are the opposite of finalizers - they allow API clients to react to object creation and populate fields prior to other clients seeing them.
High level description:
1. Add `metadata.initializers` field to all objects
2. By default, filter objects with > 0 initializers from LIST and WATCH to preserve legacy client behavior (known as partially-initialized objects)
3. Add an admission controller that populates .initializer values per type, and denies mutation of initializers except by certain privilege levels (you must have the `initialize` verb on a resource)
4. Allow partially-initialized objects to be viewed via LIST and WATCH for initializer types
5. When creating objects, the object is "held" by the server until the initializers list is empty
6. Allow some creators to bypass initialization (set initializers to `[]`), or to have the result returned immediately when the object is created.
The code here should be backwards compatible for all clients because they do not see partially initialized objects unless they GET the resource directly. The watch cache makes checking for partially initialized objects cheap. Some reflectors may need to change to ask for partially-initialized objects.
```release-note
Kubernetes resources, when the `Initializers` admission controller is enabled, can be initialized (defaulting or other additive functions) by other agents in the system prior to those resources being visible to other clients. An initialized resource is not visible to clients unless they request (for get, list, or watch) to see uninitialized resources with the `?includeUninitialized=true` query parameter. Once the initializers have completed the resource is then visible. Clients must have the the ability to perform the `initialize` action on a resource in order to modify it prior to initialization being completed.

Implement proposal kubernetes/community#363
```release-note
The Kubernetes API supports retrieving tabular output for API resources via a new mime-type `application/json;as=Table;v=v1alpha1;g=meta.k8s.io`. The returned object (if the server supports it) will be of type `meta.k8s.io/v1alpha1` with `Table`, and contain column and row information related to the resource. Each row will contain information about the resource - by default it will be the object metadata, but callers can add the `?includeObject=Object` query parameter and receive the full object. In the future kubectl will use this to retrieve the results of `kubectl get`.

Add TPR to CRD migration helper.
This is a helper for migrating TPR data to CustomResource. It's rather hacky because it requires crossing apiserver boundaries, but doing it this way keeps the mess contained to the TPR code, which is scheduled for deletion anyway.
It's also not completely hands-free because making it resilient enough to be completely automated is too involved to be worth it for an alpha-to-beta migration, and would require investing significant effort to fix up soon-to-be-deleted TPR code. Instead, this feature will be documented as a best-effort helper whose results should be verified by hand.
The intended benefit of this over a totally manual process is that it should be possible to copy TPR data into a CRD without having to tear everything down in the middle. The process would look like this:
1. Upgrade to k8s 1.7. Nothing happens to your TPRs.
1. Create CRD with group/version and resource names that match the TPR. Still nothing happens to your TPRs, as the CRD is hidden by the overlapping TPR.
1. Delete the TPR. The TPR data is converted to CustomResource data, and the CRD begins serving at the same REST path.
Note that the old TPR data is left behind by this process, so watchers should not receive DELETE events. This also means the user can revert to the pre-migration state by recreating the TPR definition.

[Federation][kubefed]: Use StorageClassName for etcd pvc
This PR updates kubefed to use the StorageClassName field [added in 1.6](http://blog.kubernetes.io/2017/03/dynamic-provisioning-and-storage-classes-kubernetes.html
) for etcd's pvc to allow the user to specify which storage class they want to use. If no value is provided to ``kubefed init``, the field will not be set, and initialization of the pvc may fail on a cluster without a default storage class configured.
The alpha annotation that was previously used (``volume.alpha.kubernetes.io/storage-class``) was deprecated as of 1.4 according to the following blog post:
http://blog.kubernetes.io/2016/10/dynamic-provisioning-and-storage-in-kubernetes.html
**Release note**:
```
'kubefed init' has been updated to support specification of the storage class (via --etcd-pv-storage-class) for the Persistent Volume Claim (PVC) used for etcd storage. If --etcd-pv-storage-class is not specified, the default storage class configured for the cluster will be used.

* Adds a new authorization mode (`Node`) that authorizes requests from nodes based on a graph of related pods,secrets,configmaps,pvcs, and pvs:
* Watches pods, adds edges (secret -> pod, configmap -> pod, pvc -> pod, pod -> node)
* Watches pvs, adds edges (secret -> pv, pv -> pvc)
* When both Node and RBAC authorization modes are enabled, the default RBAC binding that grants the `system:node` role to the `system:nodes` group is not automatically created.
* Tightens the `NodeRestriction` admission plugin to require identifiable nodes for requests from users in the `system:nodes` group.
This authorization mode is intended to be used in combination with the `NodeRestriction` admission plugin, which limits the pods and nodes a node may modify. To enable in combination with RBAC authorization and the NodeRestriction admission plugin:
* start the API server with `--authorization-mode=Node,RBAC --admission-control=...,NodeRestriction,...`
* start kubelets with TLS boostrapping or with client credentials that place them in the `system:nodes` group with a username of `system:node:<nodeName>`
```release-note
kube-apiserver: a new authorization mode (`--authorization-mode=Node`) authorizes nodes to access secrets, configmaps, persistent volume claims and persistent volumes related to their pods.
* Nodes must use client credentials that place them in the `system:nodes` group with a username of `system:node:<nodeName>` in order to be authorized by the node authorizer (the credentials obtained by the kubelet via TLS bootstrapping satisfy these requirements)
* When used in combination with the `RBAC` authorization mode (`--authorization-mode=Node,RBAC`), the `system:node` role is no longer automatically granted to the `system:nodes` group.
```
```release-note
RBAC: the automatic binding of the `system:node` role to the `system:nodes` group is deprecated and will not be created in future releases. It is recommended that nodes be authorized using the new `Node` authorization mode instead. Installations that wish to continue giving all members of the `system:nodes` group the `system:node` role (which grants broad read access, including all secrets and configmaps) must create an installation-specific ClusterRoleBinding.
```
Follow-up:
- [ ] enable e2e CI environment with admission and authorizer enabled (blocked by kubelet TLS bootstrapping enablement in https://github.com/kubernetes/kubernetes/pull/40760)
- [ ] optionally enable this authorizer and admission plugin in kubeadm
- [ ] optionally enable this authorizer and admission plugin in kube-up
