cephadm: add get_container_stats to container_types

We're in the process of trying to remove get_container_types from
cephadm.py. Most of the generic logic has been moved to
container_engines.py. However, the remaining parts of the current
get_container_stats rely on classes from container_types.py so add a
future replacement for the existing get_container_types to
container_types.py.
