Change log:

controller: save older revisions for Deployment's replica sets
@jwforres the only usable way I could find for multiple old revisions for a single replica set is to stuff them as comma-separated values.
@kubernetes/deployment this retains old revisions served by a replica set inside an annotation.
Fixes https://github.com/kubernetes/kubernetes/issues/33844

Update client config invalid option errors to be more specific
This patch adds better error handling for cases where a global option (such as --context or --cluster) causes an invalid config to be returned.
```release-note
release-note-none
```
This patch provides a more relevant error message when a client
configuration option is passed with an invalid or non-existent value.
`$ kubectl get pods --cluster="non-existent"`
```
error: No configuration file found, please login or point to an existing
file
```
`$ kubectl get pods --cluster="non-existent"`
```
error: cluster "non-existent" does not exist

Allow empty annotation values
Related downstream issue: https://github.com/openshift/origin/issues/11175
**Release note**:
```release-note
release-note-none
```
Annotations with empty values can be used, for example, in diagnostics
logging. This patch removes the client-side check for empty values in
an annotation key-value pair.
**Before**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
error: invalid annotation format: node-selector=
```
**After**
```
$ kubectl annotate pod zookeeper-1 node-selector="" --overwrite
pod "zookeper-1" annotated
```
```
$ kubectl get po/zookeeper-1 --template='{{.metadata.annotations}}'
map[... node-selector: test-label:test]
```

Integration tests: Migrate scheduler perf to the integration suite, s…
*Problem*
issues like https://github.com/kubernetes/kubernetes/pull/32384/ happen because we dont compile the integration tests as part of the build
*Solution*
This pr will make it so scheduler_perf is included in the integration tests, but it will run in short mode that only makes sure compilation happens . it also removes the over generalized test/component directory which only has one entry
```
test/integration/replicationcontroller
test/integration/scheduler
test/integration/scheduler
test/integration/scheduler_perf
test/integration/scheduler_perf
test/integration/secrets
test/integration/serviceaccount
test/integration/storageclasses

Set --alsologtostderr=true in integration test
Without the flag, no glog output are stored in the test results. The logs are useful for debugging flaky tests like https://github.com/kubernetes/kubernetes/issues/30228.
The change also reveals a lot of messages like `W0912 14:19:32.306719 25386 cacher.go:468] Terminating all watchers from cacher *api.LimitRange`, which doesn't seem right.

Namespace certificates API group
New API groups should follow best-practices for naming, including using DNS names within the k8s.io namespace
```release-note
The certificates API group has been renamed to certificates.k8s.io
```
Running tests rebuilds almost everything. Most unit tests do not need to be
rebuilt. This installs test artifacts and makes subsequent test runs as much
as 6x faster. I saw pkg/apiserver tests drop from 30+ seconds to 5 seconds.
