Title: Export OVS datapath performance counters via sFlow

The OVS cache hit/miss counters and memory/CPU usage statistics have been identified
as important metrics when managing large deployments. This patch allows them
to be pushed periodically as part of the sFlow feed, and represents a more
efficient and scalable alternative to polling via ovs-dpctl(1).
