I think for something so relevant to many plugins, I'd like to see it have its own folder for auth in the common folder, and I'd like to see support for more auth types in addition to Basic, specifically api key and maybe bearer token.

[akrantz01]

Should I be adding API key and bearer token auth along with this PR, or should it be a separate issue?
