Initial version of test for defining flows in switch and verifying that flow definitions can be read back correctly
- Tested against openvswitch-1.4.0 and Indigo
- Both are somewhat flaky, but test itself seems pretty much debugged, should not require too much more
- Some refinements still necessary, such as message timeouts
- Test code still present that limits number of flows defined, instead of filling entire flow table(s)
