Code Issues Proposed changes

Update git submodules 

* Update neutron from branch 'master'
  - Merge "Ensure drop flows on br-int at agent startup for DVR too"
  - Ensure drop flows on br-int at agent startup for DVR too
    
    Commit 90212b12 changed the OVS agent so adding vital drop flows on
    br-int (table 0 priority 2) for packets from physical bridges was
    deferred until DVR initialization later on. But if br-int has no flows
    from a previous run (eg after host reboot), then these packets will hit
    the NORMAL flow in table 60. And if there is more than one physical
    bridge, then the physical interfaces from the different bridges are now
    essentially connected at layer 2 and a network loop is possible in the
    time before the flows are added by DVR. Also the DVR code won't add them
    until after RPC calls to the server, so a loop is more likely if the
    server is not available.
    
    This patch restores adding these flows to when the physical bridges are
    first configured. Also updated a comment that was no longer correct and
    updated the unit test.
