ocfs2: export heartbeat thread pid via configfs

The patch allows the ocfs2 heartbeat thread to prioritize I/O which may
help cut down on spurious fencing. Most of this will be in the tools -
we can have a pid configfs attribute and let userspace (ocfs2_hb_ctl)
calls the ioprio_set syscall after starting heartbeat, but only cfq
scheduler supports I/O priorities now.
