cli,glusterd: Changes to cli-glusterd communication
Glusterd changes: With this patch, glusterd creates a socket file in DATADIR/run/glusterd.socket , and listen on it for cli requests. It listens for 2 rpc programs on the socket file, - The glusterd cli rpc program, for all cli commands - A reduced glusterd handshake program, just for the 'system:: getspec' command The location of the socket file can be changed with the glusterd option 'glusterd-sockfile'. To retain compatibility with the '--remote-host' cli option, glusterd also listens for the cli requests on port 24007. But, for the sake of security, it listens using a reduced cli rpc program on the port. The reduced rpc program only contains read-only procs used for 'volume (info|list|status)', 'peer status' and 'system:: getwd' cli commands. CLI changes: The gluster cli now uses the glusterd socket file for communicating with glusterd by default. A new option '--gluster-sock' has been added to allow specifying the sockfile used to connect. Using the '--remote-host' option will make cli connect to the given host & port. Tests changes: cluster.rc has been modified to make use of socket files and use different log files for each glusterd. Some of the tests using cluster.rc have been fixed.
