Files in pkg/util/mount that contain significant code implementation for
subpaths are moved to a new package at pkg/volume/util/subpath. This
move is done in order to preserve git history.
- 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

_netdev mount option is a userspace mount option and
isn't copied over when bind mount is created and remount
also does not copies it over and hence must be explicitly
used with bind mount

fix formatAndMount func issue on Windows
**What this PR does / why we need it**:
disk format code is missing in formatAndMount func on Windows, currently it only has mount related code:
b87a392b1a/pkg/util/mount/mount_windows.go (L356-L377)
format code is now here, which is not correct(invoked in `azuredisk.WaitForAttach` operation, it's not correct, these code should be in `formatAndMount` func and invoked by `MountDevice` operation finally)
b87a392b1a/pkg/volume/azure_dd/azure_common_windows.go (L100-L117)
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#63236
**Special notes for your reviewer**:
This is the first PR, in second PR, I will remove disk format code in azure_common_windows.go
b87a392b1a/pkg/volume/azure_dd/azure_common_windows.go (L100-L117)
Also need to mention that there would not be issue if following command invoked twice(by `WaitForAttach` and `formatAndMount`)
```
Get-Disk -Number 4 | Where partitionstyle -eq 'raw' | Initialize-Disk -PartitionStyle MBR -PassThru | New-Partition -AssignDriveLetter -UseMaximumSize | Format-Volume -FileSystem ntfs -Confirm:$false
```
**Release note**:
```

Kubelet should not resolve symlinks outside of mounter interface.
Only mounter interface knows, how to resolve them properly on the host.
As consequence, declaration of SafeMakeDir changes to simplify the
implementation:
from SafeMakeDir(fullPath string, base string, perm os.FileMode)
to SafeMakeDir(subdirectoryInBase string, base string, perm os.FileMode)
Users must not be allowed to step outside the volume with subPath.
Therefore the final subPath directory must be "locked" somehow
and checked if it's inside volume.
On Windows, we lock the directories. On Linux, we bind-mount the final
subPath into /var/lib/kubelet/pods/<uid>/volume-subpaths/<container name>/<subPathName>,
it can't be changed to symlink user once it's bind-mounted.

fix azure file mount limit issue on windows due to using drive letter
**What this PR does / why we need it**:
It's not necessary to use drive letter in azure file mount, correct usage for New-SmbGlobalMapping is like following:
```
New-SmbGlobalMapping -RemotePath $AzureFilePath -Credential $Credential
mklink /D $mountPath $AzureFilePath
```
I removed the `LocalPath` parameter in New-SmbGlobalMapping
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#54668
Without this PR, there is a limit(25) for azure file mount number on each node because only 25 drive letters could be used on each windows node, With this PR, there would be no such limit.

fix warning messages due to GetMountRefs func not implemented in windows
**What this PR does / why we need it**:
This PR completes the windows implementation of GetMountRefs in mount.go. In linux, the GetMountRefs implementaion is: read `/proc/mounts` and find all mount points, while in Windows, there is no such `/proc/mounts` place which shows all mounting points.
There is another way in windows, **we could walk through(by `getAllParentLinks` func) the mount path(symbolic link) and get all symlinks until we got the final device, which is actually a drive**.
**Which issue this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close that issue when PR gets merged)*: fixes#54670
This PR fixed the warnning issue mentioned in https://github.com/kubernetes/kubernetes/pull/51252
**Special notes for your reviewer**:
Some values in the code would be like follwoing:
```
GetMountRefs: mountPath ("\\var\\lib\\kubelet\\pods/4c74b128-92ca-11e7-b86b-000d3a36d70c/volumes/kubernetes.io~azure-disk/pvc-1cc91c70-92ca-11e7-b86b-000d3a36d70c")
getAllParentLinks: refs (["" "" "c:\\var\\lib\\kubelet\\plugins\\kubernetes.io\\azure-disk\\mounts\\b1246717734" "G:\\"])
basemountPath c:\var\lib\kubelet\plugins\kubernetes.io\azure-disk\mounts
got volumeID b1246717734
```
**Release note**:
```
