Add support for linuxbridge agent

Currently TripleO does not support LinuxBridge driver, setting
NeutronMechanismDrivers to linuxbridge will not force ml2 plugin
to use linuxbridge.

This commit adds new environment file which replaces default ovs
agent with linuxbridge on Compute and Controller nodes.
