Add command logging facility for glusterd
Added new command logging facility to gf_cmd_log() which can be used to log all commands to a .cmd_log_history file situated in the glusterd working directory. Accepts 1 st argument a domain string (e.g: volume, peer..) followed by msg string (similar to gf_log) Signed-off-by: shishir gowda <shishirng@gluster.com> Signed-off-by: Vijay Bellur <vijay@dev.gluster.com> BUG: 1404 (need a dump of all the op/mgmt commands) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=1404
