glusterd/svc: update pid of mux volumes from the shd process
For a normal volume, we are updating the pid from a the process while we do a daemonization or at the end of the init if it is no-daemon mode. Along with updating the pid we also lock the file, to make sure that the process is running fine. With brick mux, we were updating the pidfile from gluterd after an attach/detach request. There are two problems with this approach. 1) We are not holding a pidlock for any file other than parent process. 2) There is a chance for possible race conditions with attach/detach. For example, shd start and a volume stop could race. Let's say we are starting an shd and it is attached to a volume. While we trying to link the pid file to the running process, this would have deleted by the thread that doing a volume stop.
