We don't need to force any Ceph config file for ceph-volume based OSDs
since the 'ceph-volume activate' command mount everything at start time
in the right place.
So now, OSD will keep running normally and they will also read back
normally the default location of the ceph configuration:
/etc/ceph/ceph.conf which will allow OSDs to read any configuration
overrides.
We cannot remove the generation of that file in /var/lib/rook/osd* since
we cannot tell at the stage that triggers the generation if we run
ceph-volume or not. So let's keep it around for some time.
If you are wondering how the OSD connects to the mons this is done via
the CEPH_ARGS env variable which was introduced in
https://github.com/rook/rook/pull/3894.
