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.

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).

Without the SnapshotGroupID in the Snapshot object, Kubernetes CSI does
not know that the Snapshot belongs to a group. In that case, it allows
the deletion of the Snapshot, which should be denied.

`ensureImageCleanup()` can cause a panic when an image was deleted, but
the journal still contained a reference. By opening the IOContext before

When an `.Destroy()` is called on an rbdImage (or rbdVolume or
rbdSnapshot), the IOContext, Connection and other attributes are
invalid. When using a destroyed resource that points to an object that
was allocated through librbd, the process most likely ends with a panic.

A function called `setImageOptions()` is expected to set the passed
options on the volume. However, the passed options parameter is only
filled with the options that should get set on the RBD-image at the time
of creation.
The naming of the function, and it's parameter is confusing. Rename the
function to `constructImageOptions()` and return the ImageOptions to
make it easier to understand.

The rbd_types package was initially created with references to the rbd

This commit adds support for flattenMode option
for replication.
If the flattenMode is set to "force" in
volumereplicationclass parameters, cephcsi will
add a task to flatten the image if it has parent.
This enable cephcsi to then mirror such images after
flattening them.
The error message when the image's parent is
in trash or unmirrored is improved as well.

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

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.
