ofproto-dpif: Compute the subfacet add/del rate using coverage counters.
		
So far, the subfacet rates (e.g. add rate, del rate) are computed by
exponential moving averaging function in ofproto-dpif.c.  This commit
replaces that logic with coverage counters.  And the rates can be
checked by running "ovs-appctl coverage/show" command.

coverage: Reimplement the "ovs-appctl coverage/show" command.
		
This commit changes the "ovs-appctl coverage/show" command to show the
the averaged per-second rates for the last few seconds, the last minute
and the last hour, and the total counts of all of the coverage counters.
