Tempest: Support lbaas api & scenario tests to run against upstream

Browse Source 
NSX-v lbaas requires lbaas's network attached to an exclusive router.
To run lbaas tests on upstream implemantion, we need to remove
rotuer_type attributes at creating router.

Fixed lbaas API:
  delete-all load-balanacer resources without deleting listeners.
  wait for status function is now at load_balancers client.

Lbaas scenario tests replace urllib2 with urllib3.
