Merge lp:~vorlon/summit/oauth2-support into lp:summit

[Steve Langasek]

Preliminary support for oauth2. This pulls in a new django module dependency, and also only works if you also register and add in oauth2 keys, which you need to get from your oauth2 provider.

Initial support for Debian SSO

Simplify the oauth2 support

we don't actually need separate url handlers, we can just include the
upstream ones and set LOGIN_URL to whichever provider we want (e.g.,
/login/google-oauth2) in our individual django app. If someone really
wants to have multiple auth providers from the same app, they can figure
that out on their own, but currently it doesn't look like an interesting use
case.

Make the 'login' link on the navbar configurable via LOGIN_URL in settings.

Initial support for oauth2 (using the Google backend for testing)
