These changes are required to conform to with openstack/neutrons name changing from 'tenant' to 'project'. Our impact is minimal since we don't implement any "plugin specific" models (db tables) with 'tenant' in them. For an example of such changes made in neutron, see the depends on change listed below. Change-Id: Ife881b3d2da6dc07dc14a6d53d147e075204d83b Depends-On: I87a8ef342ccea004731ba0192b23a8e79bc382dc
