Enable igmp test to work under voltha.
Also change cordSubscriber voltha test to work with the voltha auto configure.
Import teardown_module as well in other test cases.
The tests that are not supposed to work with voltha or rely on auto configure should set:
VOLTHA_AUTO_CONFIGURE = False
in their test class.
