Add type hints

[Viicos]

As the project is now supporting Python3.7 and greater, we could add type hints. I'd be happy to work on this if this is an option.

For reference: https://typing.readthedocs.io/en/latest/source/libraries.html

Tracked PRs:

• Add type hints to base and authentication #472
• Add type hints to management #497

Hi @Viicos - thanks for the offer

We'd be happy to look at a PR, we may choose to limit the completeness of the types depending on the maintenance overhead. (eg typing the arguments required for getting a client by id, great - typing the whole response payload for every request to the management api, not maintainable for us right now)

Yes this is understandable, I'll take a deep look at the repository and describe on this issue where I'll add types
