[MINOR] print usage on the stats sockets upon invalid commands

Browse Source 
When issuing commands on the unix socket, there's no way to
know if the result is empty or if the command is wrong. This
patch makes invalid command return a help message.
(cherry picked from commit 43e0e3997870e39b78b87d3050f260571e5a7de9)
