  Log Message:
  ofproto: report coverage on hitting datapath flow limit

Whenever the number of flows in the datapath crosses above
the flow limit set/autoconfigured, it is helpful to report
this event through coverage counter for an operator/devops
engineer to know and take proactive corrections in the
switch configuration.

Today, these events are reported in ovs vswitch log when
a new flow can not be inserted in upcall processing in which
case ovs writes a warning, otherwise an auto correction
made by ovs to flush old flows without any intimation at all.
