mon: MonmapMonitor: Use default port when the specified on 'add' is zero

Fixes a bug triggered by using the ceph tool to 'mon add' with a port set
to zero. We now default to the monitor's default port (6789) instead, and
we will fail if that port is already assigned to some other monitor.

Fixes: bug #2661

- keyrings have new default locations that everyone should use.
- the user key setup is vastly simplified if you use the
  'ceph auth get-or-create' command.

filestore: sync object_map object in lfn_remove when nlink > 1

In the following sequence:

1) create (a, 1)
2) setattr (a, 1)
3) link (a, 1), (b, 1)
4) remove (a, 1)

If we play 1-4 and then replay 1-4 again, we will end up removing
(b, 1)'s attributes since nlink for (a, 1) the second time through
is 1.  We fix this by marking spos on the object_map header for
(a, 1) when we remove (a, 1) but not eh attributes.

rest-bench: mark request as complete later

We marked a request as complete in the callback, however
it might be that we're still inside S3_runall_request_context()
which means that request is not really complete yet.
Possibly fixes bug #2652.

mon: initialize quorum_features

This could cause us to incorrectly encode new features into the monstore
that an old mon won't understand.

This is overly conservative; we probably need to persist the set of quorum
features that are supported and use those.
