During PVC snapshot/clone both kms config and passphrase needs to copied,
while for PVC restore only passphrase needs to be copied to dest rbdvol
since destination storageclass may have another kms config.

This commit adds the logic to detect a passed in volumeID
is a migrated volume ID and if yes, the driver connect to the
backend cluster and clean/delete the image. The logic
only applied if its a migration volume ID. The migration volume ID
carry the information like mons, pool and image name which is
good enough for the driver to identify and connect to the backend
cluster for its operations.
migration volID format:
<mig>_mons-<monsHash>_image-<imageUID>_<poolHash>
Details on the hash values:
* MonsHash: this carry a hash value (md5sum) which will be acted as the
`clusterID` for the operations in this context.
* ImageUID: this is the unique UUID generated by kubernetes for the created
volume.
* PoolHash: this is an encoded string of pool name.

This commit add test for migration delete volID detection scenario
by passing a custom volID and with the entries in configmap changed
to simulate the situation. The staticPV function also changed its

createCustomConfigmap helps to create a custom cluster entry in

the migration nodestage request does not carry the 'clusterID' in it
and only monitors are available with the volumeContext. The volume
context flag 'migration=true' and 'static=true' flags allow us to
fill 'clusterID' from the passed in monitors to the volume Context,so
that rest of the static operations on nodestage can be proceeded as we
do treat static volumes today.

as part of migration support, the clusterID has to be fetched
from passed in mon. Because the intree RBD storage class only
got monitor and not `clusterID` parameter support. However, in
CSI, SC has the `clusterID` parameter support but not mon. Due
to that we have to fetch the clusterID from config file for the
passed in mon and use it in our operations. This adds a helper
function to retrieve clusterID from passed in mon string.

Currently, we delete the ceph client log file on unmap/detach.
This patch provides additional alternatives for users who would like to
persist the log files.
Strategies:
-----------
`remove`: delete log file on unmap/detach
`compress`: compress the log file to gzip on unmap/detach
`preserve`: preserve the log file in text format
Note that the default strategy will be remove on unmap, and these options
can be tweaked from the storage class
Compression size details example:
On Map: (with debug-rbd=20)

Currently we return a !ready status if an image
is not found when a replication resync is issued.
We also return a !ready just post issuing a resync.
The change is to ensure we return errors in these
cases for the caller to retry the operation till
we can determine we are actually resyncing, and then
return !ready with nil errors.

This commit adds capability to genVolFromVolumeOptions() to fetch
mapped clusted-id & mon ips for mirrored PVC on secondary cluster
which may have different cluster-id.
This is required for NodeStageVolume().
We also don't need to check for mapping during volume create requests,
so it can be disabled by passing a bool checkClusterIDMapping as false.
GetMonsAndClusterID() is modified to accept bool checkClusterIDMapping
based on which clustermapping is checked to fetch mapped cluster-id and
mon-ips.
