Slawek Kaplonski 4456a87dac Don't setup bridge controller if it is already set
Setting new controller for bridge every time when neutron-ovs-agent
is restarted or is doing full-sync may cause some short data plane
connectivity loss and is not needed if same controller is already
configured for the bridge.
With this patch neutron-ovs-agent will first check if controller is
configured for the bridge and if it's the same as what should be
configured, it will skip setting it up.

With this patch also protocols added to the bridge will be first checked
if they aren't already there and only missing ones will be added if
necessary.

Setting of the connectivity mode and inactivity probe is
always performed as this don't cause connectivity issues and is cheap
so we can always ensure that those parameters are configured properly.
