there can be a change we can reconcile same
PV parallelly we can endup in generating and
deleting multiple omap keys. to be on safer
side taking lock to process one volumeHandle

In the case of the Async DR, the volumeID will
not be the same if the clusterID or the PoolID
is different, With Earlier implementation, it
is expected that the new volumeID mapping is
stored in the rados omap pool. In the case of the
ControllerExpand or the DeleteVolume Request,
the only volumeID will be sent it's not possible
to find the corresponding poolID in the new cluster.
With This Change, it works as below
The csi-rbdplugin-controller will watch for the PV
objects, when there are any PV objects created it
will check the omap already exists, If the omap doesn't
exist it will generate the new volumeID and it checks for
the volumeID mapping entry in the PV annotation, if the
mapping does not exist, it will add the new entry
to the PV annotation.
The cephcsi will check for the PV annotations if the
omap does not exist if the mapping exists in the PV
annotation, it will use the new volumeID for further
operations.

In case of the DR the image on the primary site cannot be
demoted as the cluster is down, during failover the image need

Incase of resync the image will get deleted, gets

It makes sense to return aborted error instead
of not found as we have omap data only the image

Do resync if the image is in unknow or in error
state.
Check for the current image state for up+stopped
or up+replaying and also all peer site status
should be un up+stopped to confirm that resyncing
is done and image can be promoted and used.

There is no need for each EncryptionKMS to implement the same GetID()

GetKMS() is the public API that initilizes the KMS providers on demand.
Each provider identifies itself with a KMS-Type, and adds its own
initialization function to a switch/case construct. This is not well
maintainable.
The new GetKMS() can be used the same way, but uses the new kmsManager
interface to create and configure the KMS provider instances.
All existing KMS providers are converted to use the new kmsManager
plugins API.

The KMSProvider struct is a simple, extendable type that can be used to
register KMS providers with an internal kmsManager.
Helper functions for creating and configuring KMS providers will also be
located in the new kms.go file. This makes things more modular and
