Added docstring and type annotations to family(), removed parameter endpoint

[mattkeanny]

Starting with type annotations. Acc. to ops specs, endpoint is not used in family service. Not used in tests either. Options: either document it in docstring or remove it. Went for second option. The type annotations are acc. to python 3.6 (although commit comment says py3.8).

Would it help if I check out this branch and use it in my tests?
