====================
selftests: openvswitch: add flow programming cases

The openvswitch selftests currently contain a few cases for managing the
datapath, which includes creating datapath instances, adding interfaces,
and doing some basic feature / upcall tests.  This is useful to validate
the control path.

Add the ability to program some of the more common flows with actions. This
can be improved overtime to include regression testing, etc.
