Comment 2 for bug 1468779

@Sam,

Ya kolla start script may not be the appropriate place - I prefer your suggestion of having a configuration variable in the globals.yml file. Often I file bugs like these to keep track of todo items, so they are lacking in detail or are technically incorrect. We still do require some way to select between OVS and linuxbridge (and possibly other ml2 agents).

As far as kolla compose, I'd be satisified with just only offering linuxbridge, since we already have that implemented and we I believe had agreed in one of our team meetings to do functional gate testing using ansible AIO.
