  OVS agent ryu/native implementation breaks non-OF1.3 uses

  Fix Released

Bug description:
  The ryu-based OVS agent variant forces the bridge Openflow version to 1.3 
only [1], which breaks a few things:
  - troubleshooting tools relying on ovs-ofctl, unless they specify "-O 
Openflow13", will break:
    version negotiation failed (we support version 0x01, peer supports version 
    ovs-ofctl: br-tun: failed to connect to socket (Broken pipe)

  - calling add_flow on an OVSCookieBridge derived from a bridge that is
  an native.ovs_bridge.OVSAgentBridge, will fail with the same error,
  because add_flow will call ovs-ofctl without specifying "-O
  Openflow13"  (this issue is currently hitting networking-bgpvpn: [2])

  It seems like a possible fix would be to not restrict the set of
  Openflow versions supported by the bridge to Openflow13, but to just
  *add* Openflow13 to the set of supported versions.
