osd: fix OSDCap parser on old boost/spirit

* on boost 1.41, the ascii::space skipper fails to skip the spaces at the
  beginning of the parsed string, so as a workaround we replace the `lit(' ')`
  in grammar spec with `ascii::blank`. this also simplifies the grammar
  a little bit.

mon: noforward flag for commands that are not supposed to be forwarded

For not a monitor leader, if a received command is not supported
locally, but is supported by the leader, it is forwarded to the
leader.

For some commands that may have undesirable behaviour. E.g. for the
recently added "ceph tell mon.x version", if the mon.x is not a leader
and does not support "version" command yet, but the leader does, the
user will receive the version of the leader, and can't be actually
sure about a non leader version.

Fix this by adding noforward flag to commands that are not supposed to
be forwarded. Set the flag for "version" command. Although there are
other non-forwardable commands (like injectargs) it is not necessary
to add the flag to them, as the commands are too old to suffer from
the describe problem.
