The peer addr stuff via asok is a bit fragile because the user must
provide an exact addrvec matching the mon to avoid some weirdness, but
it's rarely used, and the fix would be some robustness/tolerance in the
messenger that is a bigger project than this.

When a PG is in the pending merge state it is >= pg_num_pending and <
pg_num. When this happens quiesce IO, peer, wait for activate to commit,
and then notify the mon that we are idle and safe to merge.

- Remove stream concept. it was incompletely/poorly
specified, and we dno't actually want to implement it now. We
can do it later now that we have a banner that advertises
features more clearly.
- Simplify the auth messages a bit: make a MORE message that
isn't a request (or reply), and a final DONE. DONE comes from
the server, not the client. Drop the SET_METHOD which can be
rolled into the REQUEST message.

there are 3 phases of authentication and authorization in cephx:
0. proto = CEPH_AUTH_UNKNOWN, for start the session,
create auth handlers on both sides.
1. GET_AUTH_SESSION_KEY, to get authenticated, the client will
get the session ticket at the end of this phase. the session ticket,
is actually also a service ticket for CEPH_ENTITY_TYPE_AUTH.
2. CEPHX_GET_PRINCIPAL_SESSION_KEY, to get authorized, the client
will get the requested, service tickets at the end of this phase.

This is pretty sparse because users don't really
interact with the module, they interact with other
modules that use it.

Prior to this change, the CephFS snapshot instructions were not clear
whether users should "mkdir" the ".snap" directory or not.
Update the documentation to clarify that users should make a directory
under .snap with a name of their choice.
Thanks to John Spray <jspray@redhat.com> on ceph-users for this
information.

by moving ConfigValues out of md_config_t, we are able to point
md_config_t to a new ConfigValues instance at runtime, without
destroying the old one.
also remove ConfigReader, because all md_config_obs_t will be updated
with ConfigProxy now. as md_config_t is not able to offer the *data*
anymore.
