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.

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.
