bd947bbe31 util: remove deleteLock check while acquiring snapshot createLock
snapshot controller make sure the pvc which is the source for the
snapshot request wont get deleted while snapshot is getting created,
so we dont need to check for any ongoing delete operation here on the
volume.

Subjected code path in snapshot controller:

```
pvc, err := ctrl.getClaimFromVolumeSnapshot(snapshot)
.
..
pvcClone.ObjectMeta.Finalizers = append(pvcClone.ObjectMeta.Finalizers, utils.PVCFinalizer)
_, err = ctrl.client.CoreV1().PersistentVolumeClaims(pvcClone.Namespace).Update(..)
```

b6a88dd728 rbd: add volume healer
Problem:
-------
For rbd nbd userspace mounter backends, after a restart of the nodeplugin
all the mounts will start seeing IO errors. This is because, for rbd-nbd
backends there will be a userspace mount daemon running per volume, post
restart of the nodeplugin pod, there is no way to restore the daemons
back to life.

Solution:
--------
The volume healer is a one-time activity that is triggered at the startup
time of the rbd nodeplugin. It navigates through the list of volume
attachments on the node and acts accordingly.

For now, it is limited to nbd type storage only, but it is flexible and
can be extended in the future for other backend types as needed.

From a few feets above:
This solves a severe problem for nbd backed csi volumes. The healer while
going through the list of volume attachments on the node, if finds the
volume is in attached state and is of type nbd, then it will attempt to
fix the rbd-nbd volumes by sending a NodeStageVolume request with the
required volume attributes like secrets, device name, image attributes,
and etc.. which will finally help start the required rbd-nbd daemons in
the nodeplugin csi-rbdplugin container. This will allow reattaching the
backend images with the right nbd device, thus allowing the applications
to perform IO without any interruptions even after a nodeplugin restart.

d941e5abac util: make parseTenantConfig() usable for modular KMSs
parseTenantConfig() only allowed configuring a defined set of options,
and KMSs were not able to re-use the implementation. Now, the function
parses the ConfigMap from the Tenants Namespace and returns a map with
options that the KMS supports.

The map that parseTenantConfig() returns can be inspected by the KMS,
and applied to the vaultTenantConnection type by calling parseConfig().

specified secret name and namespace(if not specified,

This behavior is followed if `secretName` key is found

`encryptionPassphrase` from storageclass secrets.
