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).
