WIP: Creating providers with config

[jhrozek]

Summary

There's a lot of changes that do work, but I'm not sure about the changes mainly to the provider interfaces. Some patches could be sent already and merged, but I wanted to get feedback on the direction.

I haven't tested other providers than github, but I don't see why they wouldn't work, we just need to have a switch/case or new enroll subcommands for them. With github you can enroll either with oauth:

minder provider enroll -c github -n my-little-oauth-github -o jakubtestorg --config /tmp/github-config.json --yes

or:

minder provider enroll -c github -n my-little-github -o jakubtestorg -t ghp_token --config /tmp/github-config.json --yes

I will point out the things I am not sure in inline comments.

this would create a provider with custom configuration.
