- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

This patch introduces glusterfsPersistentVolumeSource addition
to glusterfsVolumeSource. All fields remains same as glusterfsVolumeSource
with an addition of a new field
called `EndpointsNamespace` to define namespace of endpoint in the
spec.

The comment will ensure that only imports with
this path will compile.This is needed to make sure
that the vanity url k8s.io is used as the import path
instead of github.com.
See https://golang.org/doc/go1.4#canonicalimports
for more details.
Adds "MayRunAs" value among other group strategies. This strategy
allows to define a certain range of GIDs for FSGroupStrategy and
SupplementalGroupStrategy in a PSP.
This new strategy works similarly to the "MustRunAs" one, except that
when no GID is specified in a pod/container security context then no
GID is generated for the respective containers.
Resolves#56173
One scenario where nodeName can change for the same ip address is if
the endpoints are in hostNetwork mode and nodes are being added/deleted.
With the current validation check, if endpoints controller misses a pod
delete event, future endpoint updates will never succeed.
removed unused helper functions
Adding blank line between comment tag and package name in doc.go. So
that the comment tags such as '+k8s:deepcopy-gen=package' do not show up
in GoDoc.

Move the CloudControllerManagerConfiguration to an API group in `cmd/`
**What this PR does / why we need it**:
This PR is the last piece of https://github.com/kubernetes/kubernetes/issues/67233.
It moves the `CloudControllerManagerConfiguration` to its own `cloudcontrollermanager.config.k8s.io` config API group, but unlike the other components this API group is "private" (only available in `k8s.io/kubernetes`, which limits consumer base), as it's located entirely in `cmd/` vs a staging repo.
This decision was made for now as we're not sure what the story for the ccm loading ComponentConfig files is, and probably a "real" file-loading ccm will never exist in core, only helper libraries. Eventually the ccm will only be a library in any case, and implementors will/can use the base types the ccm library API group provides. It's probably good to note that there is no practical implication of this change as the ccm **cannot** read ComponentConfig files. Hencec the code move isn't user-facing.
With this change, we're able to remove `pkg/apis/componentconfig`, as this was the last consumer. That is hence done in this PR as well (so the move is easily visible in git, vs first one "big add" then a "big remove"). The only piece of code that was used was the flag helper structs, so I moved them to `pkg/util/flag` that I think makes sense for now.

Replace scale down window
**What this PR does / why we need it**:
Replace scale down forbidden window with scale down stabilization window.
This allows scale down based on more than one sample, to avoid rapidly changing size up and down for controllers with fluctuating load.
A bit more in https://docs.google.com/document/d/1IdG3sqgCEaRV3urPLA29IDudCufD89RYCohfBPNeWIM
This PR is copy of #67771 with resolved comments.
**Release note**:
```release-note
Replace scale down forbidden window with scale down stabilization window. Rather than waiting a fixed period of time between scale downs HPA now scales down to the highest recommendation it during the scale down stabilization window.

Increase Horizontal Pod Autoscaler update frequency to every 15s
**What this PR does / why we need it**:
PR increases Horizontal Pod Autoscaler default update interval (30s -> 15s). It will improve HPA reaction time for metric changes.

Add a ProcMount option to the SecurityContext & AllowedProcMountTypes to PodSecurityPolicy
So there is a bit of a chicken and egg problem here in that the CRI runtimes will need to implement this for there to be any sort of e2e testing.
**What this PR does / why we need it**: This PR implements design proposal https://github.com/kubernetes/community/pull/1934. This adds a ProcMount option to the SecurityContext and AllowedProcMountTypes to PodSecurityPolicy
Relies on https://github.com/google/cadvisor/pull/1967
**Release note**:
```release-note
ProcMount added to SecurityContext and AllowedProcMounts added to PodSecurityPolicy to allow paths in the container's /proc to not be masked.

Change CPU sample sanitization in HPA.
**What this PR does / why we need it**:
Change CPU sample sanitization in HPA.
Ignore samples if:
- Pod is beeing initalized - 5 minutes from start defined by flag
- pod is unready
- pod is ready but full window of metric hasn't been colected since
transition
- Pod is initialized - 5 minutes from start defined by flag:
- Pod has never been ready after initial readiness period.
**Release notes:**
```release-note
Improve CPU sample sanitization in HPA by taking metric's freshness into account.

Move volume dynamic provisioning scheduling to beta
**What this PR does / why we need it**:
* Combine feature gate VolumeScheduling and DynamicProvisioningScheduling into one
* Add allowedTopologies description in kubectl
**Special notes for your reviewer**:
Wait until related e2e and downside plugins are ready.
/hold
**Release note**:
```release-note
Move volume dynamic provisioning scheduling to beta (ACTION REQUIRED: The DynamicProvisioningScheduling alpha feature gate has been removed. The VolumeScheduling beta feature gate is still required for this feature)
