There is a typo in the endpoint group deletion, due to this you
can't remove endpoint groups once assigned. I am adding also the
unit tests to avoid this kind of issues in the future

also allows the compatibility with the future python-keystoneclient
in which the compatibility method will be removed from the
RoleManager.

pycodestyle 2.40 and later enforce these rules that were not previously
enforced. Rather than just skipping them, this cleans up the trivial
