Subject: Infra to indentify process

Problem: currently we can't identify which process is running and
how many instances of it are available.

Fix: name the process when its spawned and send it to the server
and save it in the client_t

The processes that abide by this change from this patch are:
1) fuse mount,
2) rebalance,
3) selfheal,
4) tier,
5) quota,
6) snapshot,
7) brick.
8) gfapi (by default. gfapi.<processname> if processname is found)

Note: fuse gets a process name as native-fuse-client by default.
If the user gives a name for the fuse and spawns it, it will be of
this type --process-name native-fuse-client.<name_specified>.
This can be made use by the process like aux mount done by quota,
geo-rep, etc by adding another option in the aux mount " -o
process-name=gsync_mount"

Updates: #178
