Fix deprecation warnings with _ in _i18n

Deprecation warnings began popping up in tox tests. We needed
to import the _ function from neutron._i18n . We can no longer use
the built in _ function.

ATTR_NOT_SPECIFIED was moved from neutron.api.v2 to
neutron_lib.constants . Changed imports to resolve
the deprecation warning.
