Add 'ceph-rest-api'
ceph-rest-api is a Python WSGI module for accessing the Ceph cluster.
It supports most of the commands supported by the ceph CLI,
appropriately translated to HTTP GET/PUT requests. It is not a
truly RESTful interface.
Not supported at this moment: "tell", "pg <pgid>", and "daemon"
commands.
Configuration options are specified in ceph.conf, specified with
-c/--conf or obtained from $CEPH_CONF, /etc/ceph/ceph.conf,
~/.ceph/ceph.conf, or ./ceph.conf.
-n/--name specifies the client name, used for the cluster
authentication key and for the ceph.conf section name (default
is client.restapi).
Primitive human-level command discovery is supported; GET from
BASEURL (say, http://localhost:5000/api/v0.1) will show an HTML
table of all commands and arguments, method supported, and help strings.

mon: Monitor: support multiple formatters on some status functions
Commands such as 'mon_status', 'quorum_status', 'sync_status' and
'sync_force' didn't support other formatter besides json. Regardless of
'--format=foo' being specified, they would always output in json.
This commit changes that behavior, allowing a format to be passed. These
functions do not output in plain-text however. Plain-text will default
to 'json' -- the reason: the information they provide are better outputted
in a structured fashion, and I was too lazy to come up with a plain-text
version that could be at least as good.

ceph CLI: valid() no longer returns bool, but just exception
The type validation's valid() method was using a combination of
return code and exception to really indicate the same thing;
simplify by only raising on validation error, and change callers
to cope. validate_one() follows suit.
Also, allow validate() to be called with args that are dicts
(for REST support) rather than bare words. Rules: 'name':'value'
must both match descriptor's name and validate (through valid() for
the value. If value is '', it's assumed to be the same as name,
(one can pass, for example, "detail" as one parameter to
REST, but it will still show up as {'detail':''} here).
Tweak validate()'s algorithm a bit in the process, and make
validate_command() exit the bestcmds loop immediately on first
full validation.

MonCommands: add new fields: modulename, perms, availability
To help optimize the REST API, we need to know whether the commands
are read (GET) or write (PUT/POST). However, we also could use that
same info for permission/caps checking. Add modulename/perms as
the required caps for each command to drive both needs.
The availability field is to control whether a command is displayed/
advertised through the CLI or REST interfaces; some commands aren't
really useful for REST, and we may want to invent REST-only commands;
also, this gives us a way to deprecate commands quickly and leave the
code, should that be desirable. Make the CLI display only commands
marked with the 'CLI' marker.
Also stop renaming 'help' to 'helptext' in the client.

osd: limit number of inc osdmaps send to peers, clients
We should not send an unbounded number of inc maps to our peers or clients.
In particular, if a peer is not contacted for a while, we may think they
have a very old map (say, 10000 epochs ago) and send thousands of inc maps
when the distribution shifts and we need to peer.
Note that if we do not send enough maps, the peers will make do by
requesting the map from somewhere else (currently the mon). Regardless
of the source, however, we must limit the amount that we speculatively
share as it usually is not needed.

osd: report pg stats to mon at least every N (=500) epochs
The mon needs a moderately accurate last_epoch_clean value in order to trim
old osdmaps. To prevent a PG that hasn't peered or received IO in forever
from preventing this, send pg stats at some minimum frequency. This will
increase the pg stat report workload for the mon over an idle pool, but
should be no worse that a cluster that is getting actual IO and sees these
updates from normal stat updates.
This makes the reported update a bit more aggressive/useful in that the epoch
is the last map epoch processed by this PG and not just one that is >= the
currenting interval. Note that the semantics of this field are pretty useless
at this point.
