feat: GitHub teams integration

[jpmcb]

Description

This is a WIP and likely needs some pretty deep thought on how we integrate GitHub teams into OpenSauced.

Anything beyond public teams (which, in my experience, is abnormal) raises some tricky issues around multi-tenancy and how we handle users with private teams/views.
