Subject: [PATCH] Wait and retry while getting server port and ipv4

When creating a floating IP and getting the server port and ip address(es)
it may take some seconds until the port is in 'ACTIVE' state.
In a test environment with Xen+libvirt the test failed because the port was
initially in 'DOWN' stateand after ~1s it was active.
So wait and retry to fix the test case race.
