Parsons, Cliff (cp769u) aaa85e3fc5 Refactor Ceph OSD Init Scripts - First PS
This is the first of multiple updates to ceph-osd where the OSD
init code will be refactored for better sustainability.

This patchset makes 2 changes:

1) Removes "ceph-disk" support, as ceph-disk was removed from the
   ceph image since nautilus.
2) Separates the initialization code for the bluestore, filestore,
   and directory backend configuration options.
