In general, flush in caller of dump worker rather than worker

This allows easier refactoring of workers (no dual flushes when code
changes).

ceph_argparse.py, ceph.in: validate_command: stop handling format

We were passing the entire parsed_args Namespace just to look at
and tack on 'format', and that's kinda silly; do it in the callers
instead.

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)

Unrelated: make method_dict into global METHOD_DICT

ceph_argparse, mon: make "tell <pgid>" work (duplicating "pg <pgid>")

It's a wad of special cases, but it implements "tell <pgid>" such that
it has the same effect as "pg <pgid>".
