09d848e017 rbd: make use of both listSnapshots and listChildren
Currently, CephCSI only uses listSnaps to determine
number of snapshots on a RBD image and uses snapshot
names as child image names to flatten them.
But child images may have different name(in case of
group snapshot) or they maybe in trash
(deleted k8s VolSnapshot with alive restored PVC).

The above problems are avoid by making use of both
snap and child image lists.

9936033283 rbd: consolidate snapshot flatten logic in PrepareVolumeForSnapshot()
This commit consolidates flatten logic checks for cloneDepth
and snapshotLimit in PrepareVolumeForSnapshot. This allows
the function to be called for both CreateSnapshot and
CreateVolumeGroupSnapshot.
Clone Depth check and flattening of grand parent image
now occurs before creation of snapshot starts.
This aligns better with how PVC-PVC clone and
PVC-restore process occurs currently.
Flattening the grandparent image once prevents
flattening of every newly created snapshot.
Snapshot in above para refers to k8s VolumeSnapshot
(which is backed by a rbd image).

e011e74b9d rbd: fix snapshot deletion by resolving image names correctly
When creating a Snapshot with the new NewSnapshotByID() function, the
name of the RBD-image that is created is the same as the name of the
Snapshot. The `RbdImageName` points to the name of parent image, which
causes deleting the Snapshot to delete the parent image instead.

Correcting the `RbdImageName` and setting it to the `RbdSnapName` makes
sure that upon deletion, the Snapshot RBD-image is removed, and not the
parent image.

5d5171c7d7 journal: store csi.groupid for snapshots
Commit 95733b3a9 introduced the `StoreGroupID()` function, but that
unfortunately set an empty key in the journal.

Passing the `csiGroupIDKey` key (with value `csi.groupid`) caused
setting `csi.csi.groupid` as a key. Reading the value back with the
right `csi.groupid` key always returned an empty value.
