RbdImageName before snapshot creation. This will fix the

During ResyncVolume call, discard not found
error from GetMetadata API. If the image gets
resynced the local image creation time will be
lost, if the key is not present in the image
metadata then we can assume that the image is
already resynced.

Add support to create RWX clone from the
ROX clone, in ceph no subvolume clone is
created when ROX clone is created from a
snapshot just a internal ref counter is
added. This PR allows creating a RWX clone
from a ROX clone which allows users to create
RW copy of PVC where cephcsi will identify
the snapshot created for the ROX volume and
creates a subvolume from the CephFS snapshot.

During the Demote volume store
the image creation timestamp.
During Resync do below operation
* Check image creation timestamp
stored during Demote operation
and current creation timestamp during Resync
and check both are equal and its for
force resync then issue resync
* If the image on both sides is
not in unknown state, check
last_snapshot_timestamp on the
local mirror description, if its present
send volumeReady as false or else return
error message.
If both the images are in up+unknown the
send volumeReady as true.

Set VolumeOptions.Pool parameter to empty for Snapshot-backed volumes.
This Pool parameter is optional and only used as 'pool-layout' parameter
during subvolume and subvolume clone create request in cephcsi
and not used for Snapshot-backed volume at all.
It is not saved anywhere for use in subsequent operations after create too.
Therefore, We can set it to empty and not error out.

This commit makes sure sparsify() is not run when rbd
image is in use.
Running rbd sparsify with workload doing io and too
frequently is not desirable.
When a image is in use fstrim is run and sparsify will
be run only when image is not mapped.

When a volume has AccessType=Block and is encrypted with LUKS, a resize
of the filesystem on the (decrypted) block-device is attempted. This
should not be done, as the application that requested the Block volume
is the only authoritive reader/writer of the data.
In particular VirtualMachines that use RBD volumes as a disk, usually
have a partition table on the disk, instead of only a single filesystem.
The `resizefs` command will not be able to resize the filesystem on the
block-device, as it is a partition table.
When `resizefs` fails during NodeStageVolume, the volume is unstaged and
an error is returned.
Resizing an encrypted block-device requires `cryptsetup resize` so that
the LUKS header on the RBD-image is updated with the correct size. But
there is no need to call `resizefs` in this case.

By default, `cryptsetup luksFormat` uses Argon2i as Password-Based Key
Derivation Function (PBKDF), which not only has a CPU cost, but also a memory
cost (to make brute-force attacks harder).
The memory cost is based on the available system memory by default, which in
the context of Ceph CSI can be a problem for two reasons:
1. Pods can have a memory limit (much lower that the memory available on the
node, usually) which isn't taken into account by `cryptsetup`, so it can get
OOM-killed when formating a new volume;
2. The amount of memory that was used during `cryptsetup luksFormat` will then
be needed for `cryptsetup luksOpen`, so if the volume was formated on a node
with a lot of memory, but then needs to be opened on a different node with
less memory, `cryptsetup` will get OOM-killed.
This commit sets the PBKDF memory limit to a fixed value to ensure consistent
memory usage regardless of the specifications of the nodes where the volume
happens to be formatted in the first place.
The limit is set to a relatively low value (32 MiB) so that the `csi-rbdplugin`
container in the `nodeplugin` pod doesn't require an extravagantly high memory
limit in order to format/open volumes (particularly with operations happening
in parallel), while at the same time not being so low as to render it
completely pointless.

The StagingTargetPath is an optional entry in
NodeExpandVolumeRequest, We cannot expect it to be
set always and at the same time cephcsi depended
on the StaingTargetPath to retrieve some metadata
information.
This commit will check all the mount ref and identifies
the stagingTargetPath by checking the image-meta.json
file exists and this is a costly operation as we need to
loop through all the mounts and check image-meta.json
in each mount but this is happens only if the
StaingTargetPath is not set in the NodeExpandVolumeRequest
