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 
0x04)
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.

OVS agent: configure both OF10 and OF13

This change avoids issues where a piece of code restricts
a bridge to OF13 while there is code still needing OF10, and
vice-versa, by configuring bridge to both versions.

This is aimed to be a less complex and easier to merge fix than
Id5ac7e6431c97fc70d8404b16f89533b6f270eee.
