Introduce a config option called 'mon_warn_on_pool_no_redundancy' that is
used to show a health warning if any pool in the ceph cluster is
configured with a size of 1. The user can mute/unmute the warning using
'ceph health mute/unmute POOL_NO_REDUNDANCY'.
Add standalone test to verify warning on setting pool size=1. Set the
associated warning to 'false' in ceph.conf.template under qa/tasks so
that existing tests do not break.

We already have a robust set of opt-in and opt-out procedures; no need to
require the user to enable the module.

The grace starts with the monmap creation stamp, and ceph.py does a lot
of work between creating that map and actually starting daemons (e.g.,
preparing all of the osd devices), leading to occasional MGR_DOWN errors.
Double the grace period.

Having these live in teuthology.git is silly, since they are only consumed
by the ceph task, and it is hard to revise the behavior.
Revise the behavior by adding mon_bind_* options.
