The proposed branch prevents FlatManager from executing network initialisation tasks contained in linux_net.init_host(), which are unnecessary when flat networking is used.
The proposed branch prevents FlatManager from executing network initialisation tasks contained in linux_net.init_host(), which are unnecessary when flat networking is used.

This is achieved as discussed in question #144979 (https://answers.launchpad.net/nova/+question/144979):
1) init_host in FlatManager has been overriden, thus preventing it from calling init_host in NetworkManager.
2) Also, methods related to floating IPs have been overriden in FlatManager in order to raised NotImplementedError.
