    trivial: Make driver_controller's _attrs_to_driver py3 compatible
    
    In python3 dict.values() doesn't return list but instead dict_values,
    it must be converted to list to "enjoy" list operations like insert.
    Add unit tests to be sure.

Title:
  l3_router.service_providers DriverController's _attrs_to_driver is not
  py3 compatible

Status in neutron:
  Fix Released

Bug description:
  Currently l3_router.service_providers.DriverController._attrs_to_driver has the following:
  ...
  drivers = self.drivers.values()
  # make sure default is tried before the rest if defined
  if self.default_provider:
      drivers.insert(0, self.drivers[self.default_provider])

  As in python3 dict.values() gives back "dict_values" instead of list, insert will fail with:
  "AttributeError: 'dict_values' object has no attribute 'insert'"
