glusterfsd: Make each multiplexed brick sign in

NOTE: This change will be consumed by brick mux implementation of
glusterd2 only. No corresponsing change in glusterd1 has been made.

When a multiplexed brick process is shutting down, it sends sign out
requests to glusterd for all bricks that it contains. However, sign in
request is only sent for a single brick. Consequently, glusterd has to
use some tricky means to repopulate pmap registry with information of
multiplexed bricks during glusterd restart.

This change makes each multiplexed brick send a sign in request to
glusterd2 which ensures that glusterd2 can easily repopulate pmap
registry with port information.

As a bonus, sign in request will now also contain PID of the brick
sending the request so that glusterd2 can rely on this instead of
having to read/manage brick pidfiles.
