fix race condition issue when detaching azure disk
**What this PR does / why we need it**:
add lock before detaching azure disk, without this PR, there would be lots of `Multi-Attach error` when scheduling one pod from one node to another.
**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#60101
**Special notes for your reviewer**:
@feiskyer @djsly @khenidak
Since we are using `getLunMutex.LockKey(instanceid)` for both AttachDisk and DetachDisk, there would be only one VM.update operation at a time for both AttachDisk and DetachDisk.
**Release note**:
```
fix race condition issue when detaching azure disk

StorageOS configurable device directory and mount options
**What this PR does / why we need it**:
This allows StorageOS volumes to be mounted when the kubelet is running in a container and we are unable to use the default device location (/var/lib/storageos/volumes). With this PR, the node's device location is requested via the StorageOS api, falling back to the current behaviour if not configured. The node's device location can be supplied as an environment variable (DEVICE_DIR) to the StorageOS container. This is backwards-compatible and no changes are needed to existing deployments.
The PR also allows Mount options to be set for StorageOS volumes in the same way they're enabled for other volume plugins.
The StorageOS API dependency was updated to the latest version, but no functionality changes besides adding the DeviceDir property to the Controller object.
There is also a small refactor of the loopback device handling code in storageos_utils.go to capture stderr output.
**Release note**:
```release-note
StorageOS volume plugin updated to support mount options and environments where the kubelet runs in a container and the device location should be specified.
```

csi: Remove stale volume path
**What this PR does / why we need it**:
The CSI mounter creates the following paths during SetUp():
* .../pods/\<podID\>/volumes/kubernetes.io~csi/\<specVolId\>/mount/
* .../pods/\<podID\>/volumes/kubernetes.io~csi/\<specVolId\>/volume_data.json
During TearDown(), it does not remove the `.../kubernetes.io~csi/<specVolId>/`

complains with 'Orphaned pod found, but volume paths are still present
on disk'.

Block Volume: Refactor volumehandler in operationexecutor
**What this PR does / why we need it**:
Based on discussion with @saad-ali at #51494, we need refactor volumehandler in operationexecutor

```
VolumeHandler does not need to be a separate object that is constructed inline like this.
You can create a new operation, e.g. UnmountOperation to which you pass the spec,
and it can return either a UnmountVolume or UnmapVolume.

**Special notes for your reviewer**:
1. rephrase the code logic of `CreateFileShare` func.
```
if accountName is empty, then
find a storage account that matches accountType
if no storage account found, then
create a new account
else
we only use user specified storage account
create a file share according to found storage account
```
2. Use func `getStorageAccountName` to get a unique storage account name by UUID, a storage account for azure file would be like `f0b2b0bd40c010112e897fa`. And in next PR, I will use this function to create storage account for azure disk, the storage account for azure disk would be like `d8f3ad8ad92000f1e1e88bd`.

Redesign and implement volume reconstruction work
This PR is the first part of redesign of volume reconstruction work. The detailed design information is https://github.com/kubernetes/community/pull/1601
The changes include
1. Remove dependency on volume spec stored in actual state for volume
cleanup process (UnmountVolume and UnmountDevice)
Modify AttachedVolume struct to add DeviceMountPath so that volume
unmount operation can use this information instead of constructing from
volume spec
2. Modify reconciler's volume reconstruction process (syncState). Currently workflow
is when kubelet restarts, syncState() is only called once before
reconciler starts its loop.
a. If volume plugin supports reconstruction, it will use the
reconstructed volume spec information to update actual state as before.
b. If volume plugin cannot support reconstruction, it will use the
scanned mount path information to clean up the mounts.
In this PR, all the plugins still support reconstruction (except
glusterfs), so reconstruction of some plugins will still have issues.
The next PR will modify those plugins that cannot support reconstruction
well.

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.
```
