subhamkrai 4eefad42e8 csi: move csi management to admin 
Going forward, admin will manage the csi operator
CR's and rook will only manage Ceph Connection cr
and client Profile cr.

The old csi driver is completely removed from Rook
and can no longer be used starting in Rook v1.20.

The upgrade guide will contain the needed transition steps
for managing the csi operator settings.
