ceph-volume/batch: fail on filtered devices when non-interactive

When batch is called non-interactively and a user explicitly specifies,
say a db-device, this will be filtered when unavailable. This can cause
the resulting OSD to be very different from the users intention
(standalone vs external db when the db-device was filtered). If devices
get filtered in non-interactive mode, ceph-volume should fail.

qa: force creation of fs with EC default data pool

In the future, we should add the EC data pool as a supplementary data
pool but that requires a mount to setup which is awkward in the code
here. When cephfs-shell is more widely available, this will be easier.

mon/MDSMonitor: warn when creating fs with default EC data pool

Rationale can be found in [1]. Point is that EC pools incur a
significant performance penalty when dealing with small files and xattr
updates. This is because _every_ inode has a corresponding data pool
object with backtrace information stored in its xattr.

* add check to "scrub start" command handler to dishonor request if
  multiple MDS are "active" for a recursive scrub request
* add check to MDSRank::handle_mds_map() to see if scrubbing is in
  progress and max_mds is greater than 1, if so then scrubbing is
  aborted. This is supposed to take care of the condition when scrubbing
