a35a835e9c cephfs: fix logic to call ceph fs resize
clusterAdditionalInfo map is holding a localClusterState
for checking ceph cluster supports resize and subvolumegroup
is created or not, currently we are checking if the key is present
in a map and localClusterStatelocalClusterState.resizeSupported
is set to false to call ceph fs subvolume resize to check command is
supported or not, if a structure is  initialized all its members
are set to default value. so we will never going to check the
ceph fs subvolume  resize command is supported in backend or not, we are
always using ceph fs subvolume create to resize subvolume. in some
ceph version ceph fs subvolume create wont work to resize a subvolume.
This commit changes the resizeSupported from bool to *bool for
proper handling of this scenario.

66aa595e77 cephfs: do not export internal CloneStatus type
getCloneInfo() does not need to return a full CloneStatus struct that
only has one member. Instead, it can just return the value of the single
member, so the JSON type/struct does not need to be exposed.

This makes the API for getCloneInfo() a little simpler, so it can be
replaced by a go-ceph implementation later on.

As the function does not return any of the unused attributes anymore, it
is renamed to getCloneStatu() as well.

68bd44beba rbd: add new controller to regenerate omap data
In the case of Disaster Recovery failover, the
user expected to create the static PVC's. We have
planned not to go with the PVC name and namespace
for many reasons (as in kubernetes it's planned to
support PVC transfer to a new namespace with a
different name and with new features coming in
like data populator etc). For now, we are
planning to go with static PVC's to support
async mirroring.

During Async mirroring only the RBD images are
mirrored to the secondary site, and when the
user creates the static PVC's on the failover
we need to regenerate the omap data. The
volumeHandler in PV spec is an encoded string
which contains clusterID and poolID and image UUID,
The clusterID and poolID won't remain same on both
the clusters, for that cephcsi need to generate the
new volume handler and its to create a mapping
between new volume handler and old volume handler
with that whenever cephcsi gets csi requests it
check if the mapping exists it will pull the new
volume handler and continues other operations.

The new controller watches for the PVs created,
It checks if the omap exists if it doesn't it
will regenerate the entire omap data.
