The ControllerServer should not need to care about support for
encryption, ideally it is transparantly handled by the rbdVolume type
and its internal API.
Deleting the DEK was one of the last remainders that was explicitly done
inside the ControllerServer.

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.

There is no need for each EncryptionKMS to implement the same GetID()
function. We have a VolumeEncryption type that is more suitable for

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

Helper functions for creating and configuring KMS providers will also be
