init-ceph: use SSH in "service ceph status -a" to get version
When running "service ceph status -a", a version number was never
returned for remote hosts, only for the local. This was because
the command to query the version number didn't use the do_cmd
function, which is responsible for running the command over SSH
when needed.
Modify the ceph init.d script to use do_cmd for querying the
Ceph version.

doc: mkcephfs man page, -c ceph.conf is not optional

The man page for mkcephfs and the output of mkcephfs --help
do not agree with each other. the man page says -c ceph.conf
is optional, while mkcephfs --help says it is required.
Through empirical evidence, I believe it is required. Update
the man page to make it so.

librbd: hide ENOENT on discard
AioZero, Truncate, and Remove are only used by discard and resize
operations where ENOENT can be safely ignored. If that changes in the
future, we'll need to move the enoent flag setting into discard explicitly.

osd: avoid dereferencing pg info without lock
The gen_prefix() is used for debug prefixes, but traverses data structures
that can be modified when the lock is held. Only include them in the
prefix if the lock is held; otherwise print an abbreviated prefix that is
similarly greppable to the normal output.

run-cli-tests: Check that virtualenv is found.
Commit 343cc792e847ca8901f6c08e41799a2fbbd2ca92 switched us from pip
-E to virtualenv, to keep up with the Python ecosystem, but left in
this old check for existence of "pip" as a command. We don't strictly
need that; what we need is a "virtualenv" command. PIP will be
available inside the virtualenv, by the time we get around to running
it. Check for virtualenv instead.

osd: only commit past intervals at end of parallel build

osd: explicitly requeue waiting_for_map in on_change()
Since we are requeuing stuff anyway, do it all in the correct order. This
fixes a bug where take_waiters() comes along later (at activate_map time)
and puts waiting_for_map events at the front of the queue, in front of
e.g. waiting_for_missing. This breaks ordering from the client's
perspective.
The convention should be: whenever you requeue, requeuing everything
that logically follows it first.
