As part of programming OpenvSwitch, Neutron will add to which protocols bridges support [0].
However, the Open vSwitch `ovsdb-server` process does not appear to update its perspective of which protocol versions it should support until it is restarted:

The restart of the `ovsdb-server` process above will make `ovs-vswitchd` reassess its configuration.

[Impact]
When the neutron native ovs driver creates bridges it will sometimes apply/modify the supported openflow protocols on that bridge. The OpenVswitch versions shipped with Train and Ussuri don't support this which results in OF protocol mismatches when neutron performs operations on that bridge. The patch we are backporting here ensures that all protocol versions are set on the bridge at the point on create/init.
[Test Case]
* deploy Openstack Train
* go to a compute host and do: sudo ovs-ofctl -O OpenFlow14 dump-flows br-int
* ensure you do not see "negotiation failed" errors
[Regression Potential]
* this patch is ensuring that newly created Neutron ovs bridges have OpenFlow 1.0, 1.3 and 1.4 set on them. Neutron already supports these so is not expected to have any change in behaviour. The patch will not impact bridges that already exist (so will not fix them either if they are affected).
