RBD supports creating rbd images with
object size, stripe unit and stripe count
to support striping. This PR adds the support
for the same.

In case of pre-provisioned volume the clusterID is
not set in the volume context as the clusterID is missing
we cannot extract the NetNamespaceFilePath from the
configuration file. For static volume and dynamically
provisioned volume the clusterID is set.
Note:- This is a special case to support mounting PV
without clusterID parameter.

There is not much the NFS-provisioner needs to do to expand a volume,
everything is handled by the CephFS components.
NFS does not need a resize on the node, so only ControllerExpandVolume
is required.

For the default mounter the mounter option
will not be set in the storageclass and as it is
not available in the storageclass same will not
be set in the volume context, Because of this the
mapOptions are getting discarded. If the mounter
is not set assuming it's an rbd mounter.
Note:- If the mounter is not set in the storageclass
we can set it in the volume context explicitly,
Doing this check-in node server to support backward
existing volumes and the check is minimal we are not
altering the volume context.

With cgroup v2, the location of the pids.max file changed and so did the
/proc/self/cgroup file
new /proc/self/cgroup file
`
0::/user.slice/user-500.slice/session-14.scope
`
old file:
`
11:pids:/user.slice/user-500.slice/session-2.scope
10:blkio:/user.slice

There is no directory per subsystem (e.g. /sys/fs/cgroup/pids) any more, all

In case the NFS-export has already been removed from the NFS-server, but
the CSI Controller was restarted, a retry to remove the NFS-volume will
fail with an error like:
> GRPC error: ....: response status not empty: "Export does not exist"
When this error is reported, assume the NFS-export was already removed
from the NFS-server configuration, and continue with deleting the
backend volume.

Recent versions of Ceph allow calling the NFS-export management
functions over the go-ceph API.
This seems incompatible with older versions that have been tested with

To consider the image is healthy during the Promote
operation currently we are checking only the image
state on the primary site. If the network is flaky
or the remote site is down the image health is
not as expected. To make sure the image is healthy
across the clusters check the state on both local
and the remote clusters.

Increase the timeout to 2 minutes to give enough time
for rollback to complete.
As rollback is performed by the force-promote command it,
at times, may take more than a minute
(based on dirty blocks that need to be rolled
back approximately) to rollback.
The added extra 1 minute is useful though to avoid
multiple calls to complete the rollback and in
extremely corner cases to avoid failures in the
first instance of the call when the mirror watcher
is not yet removed (post scaling down the
RBD mirror instance)
