Subject: [PATCH] use l3 flavors api def from neutron-lib

The l3 flavor extension's API definition was rehomed into neutron-lib
with commit I354911795bcd3174f73af13360ac110344a1ee8f
This patch consumes the API def by removing the rehomed code and using
the APIExtensionDescriptor for the parent class of the l3 flavors
extension.
