https://bugzilla.redhat.com/show_bug.cgi?id=1368528

From email conversation with Sage and Sam:

I don't think it is used at all, and at a minimum it is
untested and undocumented and the implementation is alomst
certainly incomplete.

I definitely support removing any trace of it from the docs.

Nathan Cutler
efc235895d doc: remove btrfs contradiction 
btrfs is not "the ideal choice for Ceph clusters" because it isn't mature and
the promised features (like deduplication) have not materialized.

The "Filesystems -> Recommended" section of this very same document (several
paragraphs) above the paragraph being modified by this commit, has been
modified to say "We used to recommend btrfs for testing, development, and any
non-critical deployments. . . . However . . . ."

This PR removes this contradiction.

b199ac6c41 doc/rados/operations/add-or-rm-mons: simplify the steps to add a mon 
this change removes the step to "ceph mon add" before starting a new
monitor. because the existing leader will start an election at seeing
the MMonJoin message sent by the new joiner, after the quorum is
archieved, the monmap will be updated with the new monitor.
so, "ceph mon add" is not necessary to add a new monitor.
moreover, this command will be blocked until a new quorum is formed,
and the proposed monmap is accepted. but in case of adding a monitor
to a single monitor cluster, the leader will wait until at least two
of the monitors reply to it. apparently, this does not happen unless
the new monitor starts. so from the user's point of view, this
command hangs until timesout, if he/she does not start the mon.b
beforehand. but this is an expected behaviour.

so, to avoid this confusion and simplify the steps to add a new
monitor. we'd better simply remove this "ceph mon add" step.
