glusterd: add a cli command to trigger a statedump on a client
With this, we will be able to trigger statedumps on remote Gluster
clients, mainly targetted for applications using libgfapi.
Design:
SIGUSR signal is the most comman way of taking a statedump in Gluster.
But it cannot be used for libgfapi based processes, as the process
loading the library might have already consumed SIGUSR signal. Hence
going by the command way.
One has to issue a Gluster command to initiate a statedump on the
libgfapi based client. The command takes hostname and PID as an
argument. All the glusterds in the cluster, check if they are connected
to the specified hostname, and send an RPC request to all the connected
clients from that hostname (via the mgmt connection).
