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.

0f8813d89f rbd:store/Read volumeID in/from PV annotation
In the case of the Async DR, the volumeID will
not be the same if the clusterID or the PoolID
is different, With Earlier implementation, it
is expected that the new volumeID mapping is
stored in the rados omap pool. In the case of the
ControllerExpand or the DeleteVolume Request,
the only volumeID will be sent it's not possible
to find the corresponding poolID in the new cluster.

With This Change, it works as below

The csi-rbdplugin-controller will watch for the PV
objects, when there are any PV objects created it
will check the omap already exists, If the omap doesn't
exist it will generate the new volumeID and it checks for
the volumeID mapping entry in the PV annotation, if the
mapping does not exist, it will add the new entry
to the PV annotation.

The cephcsi will check for the PV annotations if the
omap does not exist if the mapping exists in the PV
annotation, it will use the new volumeID for further
operations.
