Packstack - create ext net - missing v3 domains

Original commit bfc19656d00d428078c03d5bb8fe60fb1ece8366
was imported to infrared2 in 08dcc66182d630cea4fc4914e9d09ba006adbddd.

But it missed that original commit added export of project/user domains
also in create_external_network playbook for packstack.
