glusterd: clean up old port and allocate new one on every restart
GlusterD as of now was blindly assuming that the brick port which was already
allocated would be available to be reused and that assumption is absolutely
wrong.
Solution : On first attempt, we thought GlusterD should check if the already
allocated brick ports are free, if not allocate new port and pass it to the
daemon. But with that approach there is a possibility that if PMAP_SIGNOUT is
missed out, the stale port will be given back to the clients where connection
will keep on failing. Now given the port allocation always start from base_port,
if everytime a new port has to be allocated for the daemons, the port range will
still be under control. So this fix tries to clean up old port using
pmap_registry_remove () if any and then goes for pmap_registry_alloc ()
