LU-1132 protocol: reserve connect flags for new features

This patch reserves connect flags for several outstanding features:
* OBD_CONNECT_GRANT_PARAM for grant additional parameters to consume
grant more intelligently on the client side.
* OBD_CONNECT_JOBSTATS to pass a job id in ptlrpc_body.
* OBD_CONNECT_EINPROGRESS for clients that can deal with EINPROGRESS
on write.

This patch also reserves fields for the per-file data_version patch
from LU-827.
