e013cfed15 rbd: fix resync issue
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.

e54a97ba85 rbd: discover if StagingTargetPath in NodeExpandVolume
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

caf4090657 rbd: provide option to disable setting metadata on rbd images
As we added support to set the metadata on the rbd images created for
the PVC and volume snapshot, by default metadata is set on all the images.

As we have seen we are hitting issues#2327 a lot of times with this,
we start to leave a lot of stale images. Currently, we rely on
`--extra-create-metadata=true` to decide to set the metadata or not,
we cannot set this option to false to disable setting metadata because we
use this for encryption too.

This changes is to provide an option to disable setting the image
metadata when starting cephcsi.

a56f9a0c05 rbd: flatten datasource image before creating volume
This commit ensures that parent image is flattened before
creating volume.
- If the data source is a PVC, the underlying image's parent
  is flattened(which would be a temp clone or snapshot).
  hard & soft limit is reduced by 2 to account for depth that
  will be added by temp & final clone.

- If the data source is a Snapshot, the underlying image is
  itself flattened.
  hard & soft limit is reduced by 1 to account for depth that
  will be added by the clone which will be restored from the
  snapshot.

Flattening step for resulting PVC image restored from snapshot is removed.
Flattening step for temp clone & final image is removed when pvc clone is
being created.
