Update vagrant defaults with ursula dependencies

There were a few missing vagrant defaults missing; namely enable_lbaas
and the swift endpoint.  Additionally, this code had been using the cert
and key from the CI environment. This made every https call fail if it
didnt include the --insecure flag and/or some other ssl
pseudo-validation mechanism. So, just fix that.
