Fixes#66269
**Special notes for your reviewer**:
This PR use `az.VirtualMachineSizesClient.List` to list all vm sizes under region, match vm size with current node size, and then got `MaxDataDiskCount`, the `GetVolumeLimits` happens in kubelet and will return `attachable-volumes-azure-disk` in node status as following example:
```
agentpool-22082114-0
...
allocatable:
attachable-volumes-azure-disk: "8"
cpu: "2"

Add node affinity for Azure unzoned managed disks
**What this PR does / why we need it**:
Continue of [Azure Availability Zone feature](https://github.com/kubernetes/features/issues/586).
Add node affinity for Azure unzoned managed disks, so that unzoned disks only scheduled to unzoned nodes.
This is required because Azure doesn't allow attaching unzoned disks to zoned VMs.
**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 #
**Special notes for your reviewer**:
Unzoned nodes would label `failure-domain.beta.kubernetes.io/zone=0` and the value is fault domain ( while availability zone is used for zoned nodes). So fault domain is used to populate unzoned disks.
Since there are at most 3 fault domains in each region, the PR adds 3 terms for them:

Remove mount.GetMountRefs in favor of mounter.GetMountRefs
**What this PR does / why we need it**:
Currently, there are two `GetMountRefs` functions:
- `mount.GetMountRefs`: used in various volume plugins
- `<mounter>.GetMountRefs` (previously `mount.GetMountRefsByDev` introduced in [#49988](https://github.com/kubernetes/kubernetes/pull/49988/files#diff-0c0020e71c995790a90ad9c61ede7632R154), moved to `Mounter` interface in #62903)
This is confusing, and it's better to implement `GetMountRefs` on mounter interface, because different mounters can have their own implementation (especially for nsenter).
This pr removes `mount.GetMountRefs` in favor of mounter.GetMountRefs.

Part2: https://github.com/kubernetes/kubernetes/pull/63233 for API change
and the PR itself includes work based on the API change:
- Dynamic provisioning allowed topologies scheduler work
- Update provisioning interface to be aware of selected node and topology

Delegate map operation to BlockVolumeMapper plugin
**What this PR does / why we need it**:

fix data loss issue if using existing azure disk with partitions in disk mount
**What this PR does / why we need it**:
When use an existing azure disk(also called [static provisioning](https://github.com/andyzhangx/demo/tree/master/linux/azuredisk#static-provisioning-for-azure-disk)) in pod, if that disk has multiple partitions, the disk will be formatted in the pod mounting.
This PR removes `formatIfNotFormatted` func in `WaitForAttach` which uses `lsblk` command to check whether disk is formatted or not
b87a392b1a/pkg/volume/azure_dd/azure_common_linux.go (L213-L215)
And finally the format disk operation will happen in `MountDevice` in which it uses common k8s code(`SafeFormatAndMount.GetDiskFormat`) using `blkid` to detect disk format, `blkid` could detect multiple partitions
b87a392b1a/pkg/util/mount/mount_linux.go (L541-L543)
- so if we use common k8s code(`SafeFormatAndMount.GetDiskFormat`), following error will be returned for mulitple partition disks, which is expected:
