cephadm: fix base class behavior on python3.6

This fixes the cephadm test files when running tox/pytest on python3.6
(centos/rhel 8).
Long story short, combining classmethod and property on py3.6 behaves
differently from py3.7 and up. Since the classmethod is actually
unnecessary for the base class to behave as it does, we drop that
decorator.
