Public bug reported:

when parallel tempest tests are enabled, the nicira plugin is not able to create routers and set the external gateway for them.
Parallel operations indeed cause the usual eventlet/mysql deadlock in _update_router_gw_info.

The root cause for the deadlock is that the nvp api client uses eventlet
to dispatch requests.

while a solution might be to rework the API client, an easier,
backportable solution would be to specify the critical methods (ie: the
ones which then result in nvp operations which might conflict with db
operations) as synchronized.
