Unset CDPATH in build script to fix path generation

apiextensions: add subresources for custom resources
Fixes#38113Fixes#58778
**Related**:
- Proposal: https://github.com/kubernetes/community/pull/913
- For custom resources to work with `kubectl scale`: https://github.com/kubernetes/kubernetes/pull/58283
**Add types**:
- Add `CustomResourceSubResources` type to CRD.
- Fix proto generation for `CustomResourceSubResourceStatus`: https://github.com/kubernetes/kubernetes/pull/55970.
- Add feature gate for `CustomResourceSubResources`.
- Update CRD strategy: if feature gate is disabled, this feature is dropped (i.e. set to `nil`).
- Add validation for `CustomResourceSubResources`:
- `SpecReplicasPath` should not be empty and should be a valid json path under `.spec`. If there is no value under the given path in the CustomResource, the `/scale` subresource will return an error on GET.
- `StatusReplicasPath` should not be empty and should be a valid json path under `.status`. If there is no value under the given path in the CustomResource, the status replica value in the /scale subresource will default to 0.
- If present, `LabelSelectorPath` should be a valid json path. If there is no value under `LabelSelectorPath` in the CustomResource, the status label selector value in the `/scale` subresource will default to the empty string.
- `ScaleGroupVersion` should be `autoscaling/v1`.
- If `CustomResourceSubResources` is enabled, only `properties` is allowed under the root schema for CRD validation.
**Add status and scale subresources**:
- Use helper functions from `apimachinery/pkg/apis/meta/v1/unstructured/helpers.go`.
- Improve error handling: https://github.com/kubernetes/kubernetes/pull/56563, https://github.com/kubernetes/kubernetes/pull/58215.
- Introduce Registry interface for storage.
- Update storage:
- Introduce `CustomResourceStorage` which acts as storage for the custom resource and its status and scale subresources. Note: storage for status and scale is only enabled when the feature gate is enabled _and_ the respective fields are enabled in the CRD.
- Introduce `StatusREST` and its `New()`, `Get()` and `Update()` methods.
- Introduce `ScaleREST` and its `New()`, `Get()` and `Update()` methods.
- Get and Update use the json paths from the CRD and use it to return an `autoscaling/v1.Scale` object.
- Update strategy:
- In `PrepareForCreate`,
- Clear `.status`.
- Set `.metadata.generation` = 1
- In `PrepareForUpdate`,
- Do not update `.status`.
- If both the old and new objects have `.status` and it is changed, set it back to its old value.
- If the old object has a `.status` but the new object doesn't, set it to the old value.
- If old object did not have a `.status` but the new object does, delete it.
- Increment generation if spec changes i.e. in the following cases:
- If both the old and new objects had `.spec` and it changed.
- If the old object did not have `.spec` but the new object does.
- If the old object had a `.spec` but the new object doesn't.
- In `Validate` and `ValidateUpdate`,
- ensure that values at `specReplicasPath` and `statusReplicasPath` are >=0 and < maxInt32.
- make sure there are no errors in getting the value at all the paths.
- Introduce `statusStrategy` with its methods.
- In `PrepareForUpdate`:
- Do not update `.spec`.
- If both the old and new objects have `.spec` and it is changed, set it back to its old value.
- If the old object has a `.spec` but the new object doesn't, set it to the old value.
- If old object did not have a `.spec` but the new object does, delete it.
- Do not update `.metadata`.
- In `ValidateStatusUpdate`:
- For CRD validation, validate only under `.status`.
- Validate value at `statusReplicasPath` as above. If `labelSelectorPath` is a path under `.status`, then validate it as well.
- Plug into the custom resource handler:
- Store all three storage - customResource, status and scale in `crdInfo`.
- Use the storage as per the subresource in the request.
- Use the validator as per the subresource (for status, only use the schema for `status`, if present).
- Serve the endpoint as per the subresource - see `serveResource`, `serveStatus` and `serveScale`.
- Update discovery by adding the `/status` and `/scale` resources, if enabled.
**Add tests**:
- Add unit tests in `etcd_test.go`.
- Add integration tests.
- In `subresources_test.go`, use the [polymporphic scale client](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/client-go/scale) to get and update `Scale`.
- Add a test to check everything works fine with yaml in `yaml_test.go`.
**Release note**:
```release-note
`/status` and `/scale` subresources are added for custom resources.
```
In https://github.com/kubernetes/kubernetes/issues/52255, it was
determined that if the user has a CDPATH, running `make` will fail. This
is because using the KUBE_ROOT variable results in invalid paths when
the CDPATH environment variable is set.

collapse printing paths
This collapses our printers into:
1. `PrintSuccess` - which was special cased before and should really just be a flavor of printer
2. `PrintObject` - prints an object using all the defaults. This should go away once we have options on all our commands.
3. `PrinterForOptions` - which gives back a printer based on the options. This should really be a method on the options themselves.
And none of these methods have any factory dependencies anymore.

oidc authentication: switch to v2 of coreos/go-oidc
Switch to v2 of [coreos/go-oidc](https://github.com/coreos/go-oidc), which uses square/go-jose to verify tokens and supports more signing algorithms.
Most of this PR removes dependencies used by the older version of github.com/coreos/go-oidc, and updates vendor files.
This PR has been tested against tokens issued by Okta, Google, and CoreOS's dex.
Closes https://github.com/kubernetes/kubernetes/issues/57806
```release-note
kube-apiserver: the OpenID Connect authenticator can now verify ID Tokens signed with JOSE algorithms other than RS256 through the --oidc-signing-algs flag.
kube-apiserver: the OpenID Connect authenticator no longer accepts tokens from the Google v3 token APIs, users must switch to the "https://www.googleapis.com/oauth2/v4/token" endpoint.

**What this PR does / why we need it**:
Currently if integration tests fail they will print the name of the failing tests as it goes, but the summary only tells that it failed. You need to know what to look for to be able to find all these occurrences. This PR provides a summary next to the failure information, eg:
```
FAILED TESTS: run_cluster_management_tests, run_plugins_tests,

Graduate kubeletconfig API group to beta
Regarding https://github.com/kubernetes/features/issues/281, this PR moves the kubeletconfig API group to beta.
After #53088, the KubeletConfiguration type should not contain any deprecated or experimental fields, and we should not have to remove any more fields from the type before graduating it to beta.
We need the community to double check for two things, however:
1. Are there any fields currently in the KubeletConfiguration type that you were going to mark deprecated this quarter, but haven't yet?
2. Are there any fields currently in the KubeletConfiguration type that are experimental or alpha, but were not explicitly denoted as such?
Please comment on this PR if you can answer "yes" to either of those two questions. Please cc anyone with a stake in the kubeletconfig API, so we get as much coverage as possible.

Build Kubernetes binaries with valid Semantic Version
**What this PR does / why we need it**:
Refuse to build Kubernetes when a version string like `v1.8.3+xx+xx`.
This PR is to restrict the `KUBE_GIT_VERSION`, if the version string does match the rule of Semantic Version, then refuse to build.
Since Kubernetes Conformance test needs the `KUBE_GIT_VERSION` to be a valid Semantic Version, so I think it's better to restrict the version string.

Add a new environment variable to the gce startup scripts called KUBE_PROXY_MODE
**What this PR does / why we need it**:
This PR adds a new environment variable called KUBE_PROXY_MODE to the startup scripts for gce. This variable will allow a user to specify the kube-proxy implementation they want to use, with the choices being ipvs or iptables (iptables is default).

1. Need to remove use of feature gateway when IPVS goes GA
2. Need to add logic of loading required ipvs kernel modules in the scripts

Remove experimental keystone authenticator
**What this PR does / why we need it**:
experimental-keystone-url and experimental-keystone-ca-file were always
experimental. So we don't need a deprecation period.
KeystoneAuthenticator was on the server side and needed userid/password
to be passed in and used that to authenticate with Keystone. We now
have authentication and authorization web hooks that can be used. There
is a external repo with a webook for keystone which works fine along
with the kubectl auth provider that was added in:
a0cebcb559
So we don't need this older style / hard coded / experimental code
anymore.

**Special notes for your reviewer**:
**Release note**:
```release-note
kube-apiserver: the experimental in-tree Keystone password authenticator has been removed in favor of extensions that enable use of Keystone tokens.
```
rename ALLOW_SECURITY_CONTEXT to DENY_SECURITY_CONTEXT_ADMISSION to be
in line with the other admission plugins (like PSP_ADMISSION). Make
sure by default, this plugin is not enabled as well.
Use "find -exec" instead of plain "find | xargs" to fix handling of
difficult file names (such as those containing spaces). Also, use
"mapfile" for creating the array from the output instead of letting the
shell split the results into the array. Add double quotes to places
where variable handling needs it to prevent splitting and globbing.
The current code
if ! [[ " ${INTERNAL_DIRS[@]:-} " =~ " ${int_group} " ]]; then
is broken because the array is concatenated in [[ .. ]] structure. This
means that the match will be done to any substring in the resulting
string which just happens to include ${int_group}. Fix this to use a
loop instead, and do exact matching. Also make tabs consistent in the
for loop.
Use "mapfile" and "read" to split the $KUBE_AVAILABLE_GROUP_VERSIONS
string into an array using space as the delimiter. This prevents shell
from globbing and splitting the string in potentially wrong places.

Remove /ui/ redirect
The existing kube-apiserver hard-codes `/ui` to redirect to an optional add-on, which is not appropriate. It does not work in the following scenarios:
* https-enabled dashboards
* the dashboard is deployed to a different namespace or service name
* the dashboard is not installed at all
* authorization is enabled and does not allow access to /ui
This PR removes the hard-coded `/ui` redirect.
```release-note
apiserver: the /ui kube-dashboard redirect has been removed. Follow instructions specific to your deployment to access kube-dashboard
```
Use double quotes around variables in places where they might be
used in globbing. Also replace an "echo | sed" construct with bash
variable substitution.
You can compare the variable substitution with this example:
$ addresses="foo;bar,test"
$ for token in $(echo $addresses | sed 's/[,;]/\n/g'); do echo "token: $token"; done
token: foo
token: bar
token: test
$ for token in ${addresses//[,;]/' '}; do echo "token: $token" ; done
token: foo
token: bar
token: test
The SSH_PID variable doesn't get expanded in the trap because of the
single quotes. Change to double quotes.
This is an example how the change works:
$ FOO="bar"
$ echo '$FOO'
$FOO
$ echo "$FOO"
bar

```release-note
NONE
```
`kubectl get <resource> --watch` only supports watching a single resource kind at a time.
This check fails if more than one resource `Info` is returned.
When dealing with large quantities of a single resource kind, or an amount that exceeds the value of `--chunk-size`, more than one request is made to the server causing a resource `Info` to be created for each of the requests, ultimately causing the above check to fail even though we are dealing with the same type of resource.
This patch modifies that check to take into account the GVKs of all infos returned, and only fail if at least one differs.

currently the pgrep check does not allow any etcd process to exist
other than the one we intend to start in our scripts. All we need
to know is if the port is free. So let us use netstat to check
if anyone is using that port. We don't really need to know if there
is another instance of etcd is running or not.

bazel: support using SOURCE_DATE_EPOCH to override date
**What this PR does / why we need it**: ports #48708 to apply to the bazel build as well.
Note that bazel already sets `BUILD_TIMESTAMP` using `SOURCE_DATE_EPOCH`, but we have our own timestamp variable, so we need to fix it too.
We could combine this with something like
```shell
SOURCE_DATE_EPOCH=$(git log -1 --format=%cd --date=format:%s)
```
to get closer to repeatable builds. (This uses the timestamp from the last git commit.)

2nd try at using a vanity GCR name
The 2nd commit here is the changes relative to the reverted PR. Please focus review attention on that.
This is the 2nd attempt. The previous try (#57573) was reverted while we
figured out the regional mirrors (oops).
New plan: k8s.gcr.io is a read-only facade that auto-detects your source
region (us, eu, or asia for now) and pulls from the closest. To publish
an image, push k8s-staging.gcr.io and it will be synced to the regionals
automatically (similar to today). For now the staging is an alias to
gcr.io/google_containers (the legacy URL).
When we move off of google-owned projects (working on it), then we just
do a one-time sync, and change the google-internal config, and nobody
outside should notice.
We can, in parallel, change the auto-sync into a manual sync - send a PR
to "promote" something from staging, and a bot activates it. Nice and
visible, easy to keep track of.
xref https://github.com/kubernetes/release/issues/281
TL;DR:
* The new `staging-k8s.gcr.io` is where we push images. It is literally an alias to `gcr.io/google_containers` (the existing repo) and is hosted in the US.
* The contents of `staging-k8s.gcr.io` are automatically synced to `{asia,eu,us)-k8s.gcr.io`.
* The new `k8s.gcr.io` will be a read-only alias to whichever regional repo is closest to you.
* In the future, images will be promoted from `staging` to regional "prod" more explicitly and auditably.
```release-note
Use "k8s.gcr.io" for pulling container images rather than "gcr.io/google_containers". Images are already synced, so this should not impact anyone materially.
Documentation and tools should all convert to the new name. Users should take note of this in case they see this new name in the system.
```

experimental-keystone-url and experimental-keystone-ca-file were always
experimental. So we don't need a deprecation period.
KeystoneAuthenticator was on the server side and needed userid/password
to be passed in and used that to authenticate with Keystone. We now
have authentication and authorization web hooks that can be used. There
is a external repo with a webook for keystone which works fine along
with the kubectl auth provider that was added in:
a0cebcb559
So we don't need this older style / hard coded / experimental code
anymore.

This also incorporates the version string into the package name so
that incompatibile versions will fail to connect.
Arbitrary choices:
- The proto3 package name is runtime.v1alpha2. The proto compiler
normally translates this to a go package of "runtime_v1alpha2", but
I renamed it to "v1alpha2" for consistency with existing packages.
- kubelet/apis/cri is used as "internalapi". I left it alone and put the
public "runtimeapi" in kubelet/apis/cri/runtime.

- third_party: this is a tricky mix of stuff like forked code.. mostly handled by the likes of @thockin, @lavalamp, or @smarterclayton for approvals.
- Godep/vendor: Right now @thockin mostly approves these as there are some tricky pieces around ensuring the licenses are compliant. For these, I've created a vendor-(reviewers|approvers) aliases, and associated those with both the Godeps and vendor folders. Right now @thockin is the only person in them, but that can easily expand in the future if there is a documented process on what to look for when approving dependency bumps.

Promote v1alpha1 meta to v1beta1
No code changes, just renames. We can discuss if there are any field / naming changes here or in a follow-up
Parent #58536Fixes#53224
Prereq to #55637
@kubernetes/sig-api-machinery-pr-reviews @deads2k
```release-note
The `meta.k8s.io/v1alpha1` objects for retrieving tabular responses from the server (`Table`) or fetching just the `ObjectMeta` for an object (as `PartialObjectMetadata`) are now beta as part of `meta.k8s.io/v1beta1`. Clients may request alternate representations of normal Kubernetes objects by passing an `Accept` header like `application/json;as=Table;g=meta.k8s.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`. Older servers will ignore this representation or return an error if it is not available. Clients may request fallback to the normal object by adding a non-qualified mime-type to their `Accept` header like `application/json` - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response.

Use node-e2e framework for testing cadvisor
**What this PR does / why we need it**:
With cadvisor checked out in your gopath, we can now run cadvisor integration tests: `make test-e2e-node TEST_SUITE=cadvisor`.
This has a number of advantages:
* we can use the same images to test both, configured the same way.
* we will now get cadvisor logs from the integration test.
* we can now use the familiar node-e2e arguments to specify images to test with cadvisor
* no more managing snowflake VMs for cadvisor.
**Special notes for your reviewer**:
cadvisor doesnt currently produce junit* files, so I removed that as a requirement.
This wont actually work until https://github.com/google/cadvisor/pull/1868 is merged as well.

Only run verify-staging-godeps if staging/godeps are touched
**What this PR does / why we need it**:
I had a lightbulb moment. On presubmit, we only verify godeps if one of the following is changed:
- The godep scripts
- The Godeps/ dir
- The vendor/ dir
The same should apply to verifying the staging godeps, adding in the staging dir itself. The logic being, if we don't touch Godeps/vendor, we don't touch the script that generates stuff, and we don't make changes to the staging dir itself (like adding/removing imports), then we don't need to verify godeps.
Note that post-submit CI jobs will still check these, as I'm copying the same logic that's in verify-godeps
This seems too easy, so *please* point out if I'm missing something.
