ceph-rest-api: clean up options/environment
ceph-rest-api:
* create app from wrapper by calling generate_app()
* pass args to generate_app() (early parsed in wrapper)
* parse -i/--id here as well
* set addr:port on returned app object
* handle only EnvironmentError exceptions; let others spew traceback
* turn off debug when running singlethreaded server
ceph_rest_api.py:
* put glob.* on app.ceph_* instead; pass around app in init code
* drop conf parsing (let librados do its job)
Documentation updated to match.

ceph_rest_api.py: obtain and handle tell <osd-or-pgid> commands
Contact an OSD that's up to get a list of the commands, and use
them to add to the URL map.
Special treatment throughout for these commands:
* hack the help signature dump
* keep a 'flavor' per command to allow special handler() processing
* strip off 'tell/<target>' when constructing command
* allow multiple dicts with the same url
(the parameters and get/put methods can change)
* because of above, method must be validated in handler()
* validate the given OSD
* calculate target for command (mon, osd, pg)

mon/PGMonitor: reset in-core PGMap if on-disk format changes
We might have a sequence like:
- start mon, load pgmap 100
- sync
- including a format upgrade at say v 150
- refresh
- see format_version==1, and try read pgmap:101 as new format
This simply clears our in-memory state if we see that the format has
changed. That will make update_from_paxos reload the latest and prevent
it from walking through the old and useless inc updates.
Note: this does not affect the auth monitor because we unconditionally
load the latest map in update_from_paxos on upgrade. Also, the upgrade
there wasn't a format change--just a translation of cap strings from the
old to new style.

mon/Paxos: share uncommitted value when leader is/was behind
If the leader has and older lc than we do, and we are sharing states to
bring them up to date, we still want to also share our uncommitted value.
This particular case was broken by b26b7f6e, which was only contemplating
the case where the leader was ahead of us or at the same point as us, but
not the case where the leader was behind. Note that the call to
share_state() a few lines up will bring them fully up to date, so
after they receive and store_state() for this message they will be at the
same lc as we are.

rgw: expose the version of synced items to the poster
To support this, we add an optional out argument to
RGWMetadatManager::put() and fill in the read_version. When the
function returns, that contains whatever the current on-disk version
of the object is (either what already existed or what we just wrote).
Add new STATUS_APPLIED, then specify the RGWX_UPDATE_STATUS header
based on that return code when doing metadata puts.
Add a send_response() function to RGWOp_Metadata_Put in order to
support sending back our new headers. Move the translation from
STATUS_NO_APPLY from set_req_state_err() to this function, so we
can turn different sync results into failures if necessary elsewhere.
rgw: add preliminary support for sync update policies on metadata sync
We want to be able to conditionally apply new updates:
1) if we already have a newer version than the sync is applying for some
reason (replay of logs?), we don't want to go back in time.
2) If both zones were active at the same time, then we'd like to be
able to do a merge based on timestamps.
In order to support this, we add a sync_type flag to the implementations of
RGWMetadataHandler::put, and then check the version or the mtime of the
incoming put to what we have on disk, and refuse the update if needed.
We return the 204 NoContent success code when refusing sync; for the
moment the conversion is automatic but we're going to pull it out in
the next couple commits.
This commit does not complete the feature: we don't provide an interface
for specifying a different sync protocol.
Also increase fd limit defaults to accomodate the larger number
of fds.
