use ml2 driver api from neutron-lib

The ml2 plugin driver API was rehomed into neutron-lib with commit
Ifc829953ef4d5859c3475903965dc08aba42fd9c and the API was shimmed in
neutron with I86a10091b55d1123e8d16f16155e0312bb10e54c. This patch
consumes the ML2 driver api from neutron lib thereby removing the
driver_api module from neutron.
