Merge branch 'Openvswitch-meter-action'

Andy Zhou says:

====================
Openvswitch meter action

This patch series is the first attempt to add openvswitch
meter support. We have previously experimented with adding
metering support in nftables. However 1) It was not clear
how to expose a named nftables object cleanly, and 2)
the logic that implements metering is quite small, < 100 lines
of code.

With those two observations, it seems cleaner to add meter
support in the openvswitch module directly.
