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).

Remove the kube-discovery binary from the tree
**What this PR does / why we need it**:
kube-discovery was a temporary solution to implementing proposal: https://github.com/kubernetes/community/blob/master/contributors/design-proposals/bootstrap-discovery.md
However, this functionality is now gonna be implemented in the core for v1.6 and will fully replace kube-discovery:
- https://github.com/kubernetes/kubernetes/pull/36101
- https://github.com/kubernetes/kubernetes/pull/41281
- https://github.com/kubernetes/kubernetes/pull/41417
So due to that `kube-discovery` isn't used in any v1.6 code, it should be removed.
The image `gcr.io/google_containers/kube-discovery-${ARCH}:1.0` should and will continue to exist so kubeadm <= v1.5 continues to work.

Fix godep race in local builds
**What this PR does / why we need it**:
This fixes a small race condition when building a godep version other than the latest. As you're building godep once, and then building it again after checkout, this can cause inconsistency in the version selected for use. This fix tells the first `go get` to only download and not build. Then we build manually after checking out the target version.

Updating kubectl to send delete requests with orphanDependents=false if --cascade is true
Ref https://github.com/kubernetes/kubernetes/issues/40568#38897
Updating kubectl to always set `DeleteOptions.orphanDependents=false` when deleting a resource with `--cascade=true`.
This is primarily for federation where we want to use server side cascading deletion.
Impact on kubernetes: kubectl will do another GET after sending a DELETE and wait till the resource is actually deleted. This can have an impact if the resource has a finalizer. kubectl will wait till the finalizer is removed and then the resource is deleted, which is the right thing to do but a notable change in behavior.

This adds a new stand-alone certificates controller for use on GKE. It

private key locally.
It does not aim for 100% feature parity with kube-controller-manager

Promote TokenReview to v1
Peer to https://github.com/kubernetes/kubernetes/pull/40709
We have multiple features that depend on this API:
- [webhook authentication](https://kubernetes.io/docs/admin/authentication/#webhook-token-authentication)
- [kubelet delegated authentication](https://kubernetes.io/docs/admin/kubelet-authentication-authorization/#kubelet-authentication)
- add-on API server delegated authentication
The API has been in use since 1.3 in beta status (v1beta1) with negligible changes:
- Added a status field for reporting errors evaluating the token
This PR promotes the existing v1beta1 API to v1 with no changes
Because the API does not persist data (it is a query/response-style API), there are no data migration concerns.
This positions us to promote the features that depend on this API to stable in 1.7

HPA v2 (API Changes)
**Release note**:

Introduces an new alpha version of the Horizontal Pod Autoscaler including expanded support for specifying metrics.
```
Implements the API changes for kubernetes/features#117.
This implements #34754, which is the new design for the Horizontal Pod Autoscaler. It includes improved support for custom metrics (and/or arbitrary metrics) as well as expanded support for resource metrics. The new HPA object is introduces in the API group "autoscaling/v1alpha1".
Note that the improved custom metric support currently is limited to per pod metrics from Heapster -- attempting to use the new "object metrics" will simply result in an error. This will change once #34586 is merged and implemented.

Build release tars using bazel
**What this PR does / why we need it**: builds equivalents of the various kubernetes release tarballs, solely using bazel.
For example, you can now do
```console
$ make bazel-release
$ hack/e2e.go -v -up -test -down
```
**Special notes for your reviewer**: this is currently dependent on 3b29803eb5, which I have yet to turn into a pull request, since I'm still trying to figure out if this is the best approach.
Basically, the issue comes up with the way we generate the various server docker image tarfiles and load them on nodes:
* we `md5sum` the binary being encapsulated (e.g. kube-proxy) and save that to `$binary.docker_tag` in the server tarball
* we then build the docker image and tag using that md5sum (e.g. `gcr.io/google_containers/kube-proxy:$MD5SUM`)
* we `docker save` this image, which embeds the full tag in the `$binary.tar` file.
* on cluster startup, we `docker load` these tarballs, which are loaded with the tag that we'd created at build time. the nodes then use the `$binary.docker_tag` file to find the right image.
With the current bazel `docker_build` rule, the tag isn't saved in the docker image tar, so the node is unable to find the image after `docker load`ing it.
My changes to the rule save the tag in the docker image tar, though I don't know if there are subtle issues with it. (Maybe we want to only tag when `--stamp` is given?)
Also, the docker images produced by bazel have the timestamp set to the unix epoch, which is not great for debugging. Might be another thing to change with a `--stamp`.
Long story short, we probably need to follow up with bazel folks on the best way to solve this problem.

Add options for build container rsync optimization
KUBE_RSYNC_COMPRESS env var sets rsync compression level.
KUBE_RSYNC_GENERATED_TO_BUILD_CONTAINER env var disables rsyncing
generated files to build containers.
Why KUBE_RSYNC_COMPRESS is needed -- from rsync manual on `--compress` option (implied by non-zero `--compress-level`):
> Note that this option typically achieves better compression ratios than can be achieved by using a compressing remote shell or a compressing transport because it takes advantage of the implicit information in the matching data blocks that are not explicitly sent over the connection.
Use case for `KUBE_RSYNC_GENERATED_TO_BUILD_CONTAINER`: when you sometimes build stuff locally (e.g. `make WHAT=cmd/kubectl`) and sometimes do it on remote docker (`build-tools/run.sh make WHAT=cmd/hyperkube`), local builds touch generated files which causes them to be rsynced to the build data container, which may slow down the builds. Still, I'm not sure whether local->remote rsync of generated files is useful (e.g. someone may want to edit generated files for debugging purposes?), so I made not rsyncing these files an option instead of forcing such behavior.

gce... not the desired outcome for a local test setup.
We also need to sync the kubectl config in the script with the instructions for users, since if people don't test with DNS enabled, it bitrots (which this aims to fix).
To test manually, run something like
```
sudo KUBE_ENABLE_CLUSTER_DNS=true API_HOST_IP=0.0.0.0 ./hack/local-up-cluster.sh
```
The API_HOST_IP=0.0.0.0 is required, otherwise the master is not contactable by kubedns, and the dns pod will fail readychecking on the healthz pod.

Prevent SIGPIPE errors causing the version check line to fail
The way we use pipe in hack/lib/etcd.sh when processing the version command can lead to
141 failues on some systems. Using a prefix of tail can prevent this.

Fix the PATH that install-etcd.sh tells you to use
After you run install-etcd.sh, it tells you:
etcd v3.0.14 installed. To use:
export PATH=${PATH}:/home/danw/rh/go/src/k8s.io/kubernetes/third_party/etcd
which doesn't work if you have an older etcd installed in /usr/bin:
danw@w541:kubernetes (master)> PATH=${PATH}:/home/danw/rh/go/src/k8s.io/kubernetes/third_party/etcd etcd --version
etcd Version: 2.2.5
You need to put the local etcd dir first in PATH, not last.

Moved gobindata, refactored ReadOrDie refs
**What this PR does / why we need it**: Having gobindata inside of test/e2e/framework prevents external projects from importing the framework. Moving it out and managing refs fixes this problem.

--export flag belongs to kubectl get, not kubectl
**What this PR does / why we need it**:
When running the kubectl via symlink to hyperkube, the ``--export`` flag is not delegated to `kubectl get` but to `kubectl` only. Ending with unrecognized flag.
- Remaining spaghetti untangled
- Missed bazel update and a few hardcoded refs
- New instance of framework.ReadOrDie reference removed post rebase
- Resolve new clientset rebase
- Fixed e2e/generated BUILD dep
- A space
- Missed gobindata ref in golang.sh

Build vendored copy of go-bindata and use that in go generate step
**What this PR does / why we need it**: as the title says, uses the vendored version of `go-bindata` rather than expecting developers to `go get` it (when building outside docker).
**Which issue this PR fixes**: fixes#34067, partially addresses #36655
**Special notes for your reviewer**: we still call `go generate` far too many times:

- Fix unbound variables in hack/local-up-cluster.sh
- explicitly set KUBERNETES_PROVIDER in local-up-cluster.
The default appears to be gce now, so this tries to spawn a service

- Remove stale creation of kube-system: the kube-system namespace is
built in these days.
- Pickup third party etcd automatically.
- Retab hack/local-up-cluster.sh for consistency
- Update hack-local-up's internal credentials to match the user
instructions we give (which work).
- Note the CA root requirement in local-up-cluster
- Fix a dangling comment in local-up-cluster
To test manually, run something like:
```sudo KUBE_ENABLE_CLUSTER_DNS+true API_HOST_IP=0.0.0.0

Add --force to kubectl delete and explain force deletion
--force is required for --grace-period=0. --now is == --grace-period=1.
Improve command help to explain what graceful deletion is and warn about
force deletion.
Part of #34160 & #29033
```release-note
In order to bypass graceful deletion of pods (to immediately remove the pod from the API) the user must now provide the `--force` flag in addition to `--grace-period=0`. This prevents users from accidentally force deleting pods without being aware of the consequences of force deletion. Force deleting pods for resources like StatefulSets can result in multiple pods with the same name having running processes in the cluster, which may lead to data corruption or data inconsistency when using shared storage or common API endpoints.

Adds a verify script to help people writing APIs remember to wire all the individual pieces up. Eventually it will be better to avoid this altogether, but this is a start.

Build: Use checksum to rsync results
If dependencies are touched, the Makefile will detect that tools like
deepcopy-gen need to be rebuilt. It will rebuild them, but if Go decides the
dependencies are not ACTUALLY updated (maybe it was a test file - known
limitation of the current Makefile), it does not touch the resulting binary.
The Makefile touches the result explicitly to mark that the dep change has
been handled. But rsync blows away that change with the older file, and
helpfully preserves the timestamp. This repeats on every build.
Now rsync ignores it if the checksum is the same. Result = faster build.

Retry curl when it failed during download
Fixes#34769
For now I'm adding retry only to etcd installation as I saw it recently to fail in one of my PRs. We may change it also in other places if it also happens.
Generate a kubeconfig for use with controller-manager, kubelet,
scheduler etc. This kubeconfig should use the secure https
port of the api server with appropriate ca cert for the components
to talk to api server.
With this change, one can set API_PORT=0 to completely switch off
insecure access for testing admission controllers etc.

build: Fix version generation.
This PR provides update to version string generation procedure to handle additional case - working on branch delivered from release tag, instead of working on `-(alpha|beta).no` suffixed tag.
Reason of it is that actually if someone would start working on branch forked from release tag (`v1.4.1` for example), will add some commits and then would try to build k8s/run conformance tests - will end up with broken version string in form similar to `v1.4.1.X+YYYY` where `X` is a dictance/number of commits from base tag and `YYYY` will be first 14 characters from commit hash.
Such version - containing four dotted parts is rejected during conformance tests with error similar to:
```
/go/src/k8s.io/kubernetes/_output/dockerized/go/src/k8s.io/kubernetes/test/e2e/kubectl.go:843
Oct 11 12:38:33.726: Failed to get server version: Unable to parse server version "v1.4.1.5+somecommithash": Invalid character(s) found in patch number "1.5"
/go/src/k8s.io/kubernetes/_output/dockerized/go/src/k8s.io/kubernetes/test/e2e/framework/util.go:413
```
This PR provides a cure for this situation creating version string in form `v1.4.1-X+YYYY` which then should be readable for version validation checks.
Release note:
```release-note
Fix version string generation for local version different from release and not based on `-alpha.no` or `-beta.no` suffixed tag.

Fix a typo in openapi spec generation
A typo in util.sh resulted in the wrong spec stored in source tree. The commit should be explanatory.
We weren't getting incremental builds because of new test only subpackages. Our
voodoo combo of 'go install' and 'go test -c' didn't cache things like
'test/e2e_node/services'. Add the '-i' flag to 'go test' to install test only
dependencies too.

Use patched golang1.7.1 for cross-builds targeting darwin
This PR extends #32517 to use the patched go1.7.1 introduced by that PR to build all darwin targets (e.g. kubectl).
This is necessary because binaries built with earlier versions of Go regularly segfault on macOS Sierra (see #32999 and #33070).
This solution is somewhat hacky, but we intend to cherry-pick this to 1.4, and switching all of 1.4 to build with go1.7.1 is very high risk.
I haven't yet pushed the cross build image yet, so this will fail to build. Will test locally and update with results.
First step of fixing #33801.

Add separate build process for node test.
This PR is part of https://github.com/kubernetes/kubernetes/pull/31093. However, because currently node e2e is built on `KUBE_TEST_PLATFORMS`, which includes linux/amd64, darwin/amd64, windows/amd64 and linux/arm, it caused #32251 to fail.
In fact, node e2e is running on the same node with kubelet, and it also has built-in apiserver, etcd and namespace controller. All of them are only built on `KUBE_SERVER_PLATFORMS`, so node e2e should also only be built on those platforms.
```
KUBE_SERVER_PLATFORMS=(
linux/amd64
linux/arm
linux/arm64
)
```
This PR added a separate build process for node e2e to address this.
@vishh Do you need this for v1.4? because this blocks your #32251. /cc @dchen1107
