Serve OpenAPI spec with single /openapi/v2 endpoint
**What this PR does / why we need it**:
We are deprecating format-separated endpoints (`/swagger.json`, `/swagger-2.0.0.json`, `/swagger-2.0.0.pb-v1`, `/swagger-2.0.0.pb-v1.gz`) for OpenAPI spec, and switching to a single `/openapi/v2` endpoint in Kubernetes 1.10. The design doc and deprecation process are tracked at: https://docs.google.com/document/d/19lEqE9lc4yHJ3WJAJxS_G7TcORIJXGHyq3wpwcH28nU
Requested format is specified by setting HTTP headers
header | possible values
-- | --
Accept | `application/json`, `application/com.github.proto-openapi.spec.v2@v1.0+protobuf`
Accept-Encoding | `gzip`
This PR changes dynamic_client (and kubectl as a result) to use the new endpoint. The old endpoints will remain in 1.10 and 1.11, and get removed in 1.12.

action required: Deprecate format-separated endpoints for OpenAPI spec. Please use single `/openapi/v2` endpoint instead.

use GetUniqueVolumeNameFromSpec instead of implementing it manually for kubelet volume manager
**What this PR does / why we need it**:
`volumeName` is only used for attachable plugin, so we should resolve it inside the `if` statement. Besides, we can use the already exist `GetUniqueVolumeNameFromSpec` mthod instead of invoking `GetVolumeName` and `GetUniqueVolumeName` manually.

```release-note

Return missing ClusterID error instead of ignoring it
This fixes issue #57382. In the cases I'm aware of kubelet cannot function if it can't detect the cluster it is running in, so the error should be passed up to the caller preventing initialization when kubelet would fail. This way the error can be detected and kubelet startup attempted again later (giving AWS time to apply the tags).
```release-note
On AWS kubelet returns an error when started under conditions that do not allow it to work (AWS has not yet tagged the instance).

dockershim: don't check pod IP in StopPodSandbox
We're about to tear the container down, there's no point. It also suppresses
an annoying error message due to kubelet stupidity that causes multiple
parallel calls to StopPodSandbox for the same sandbox.
docker_sandbox.go:355] failed to read pod IP from plugin/docker: NetworkPlugin cni failed on the status hook for pod "docker-registry-1-deploy_default": Unexpected command output nsenter: cannot open /proc/22646/ns/net: No such file or directory
1) A first StopPodSandbox() request triggered by SyncLoop(PLEG) for
a ContainerDied event calls into TearDownPod() and thus the network
plugin. Until this completes, networkReady=true for the
sandbox.
2) A second StopPodSandbox() request triggered by SyncLoop(REMOVE)
calls PodSandboxStatus() and calls into the network plugin to read
the IP address because networkReady=true
3) The first request exits the network plugin, sets networReady=false,
and calls StopContainer() on the sandbox. This destroys the network
namespace.
4) The second request finally gets around to running nsenter but
the network namespace is already destroyed. It returns an error
which is logged by getIP().

Increase timeout of integration tests
**What this PR does / why we need it**:
In #24509 we intended to increase the timeout to 600s, but it was reverted by accident in #57521 when overriding of the value was enabled. The jenkins job should honor the default of 600s instead of continuing to override it to 300s.
This lead to flaky integration tests, specifically TestCRDDeletionCascading
