pybind/mgr: use black & isort on the smb module

Provide tox envs that check or reformat code with black and isort,
currently applied to only the new smb module.
This is similar to what we recently did for enabling tox in the
cephadmlib dir as it only applies to new code. However, other modules
that want to opt-in to automated, python-community-wide typical,
stop-thinking-and-let-tools-do-it approach to code formatting can
be added to the new envs later on.
