[PLUGIN][OAuth2] Start adding OAuth2 support with client registration

This hardcodes the user, and has some other issues, so it is not yet complete. We follow mastodon's spec for automatic client registration, available at both `/api/v1/apps` and a more reasonable `/oauth/client`. This accepts a JSON POST with the client info and returns JSON with a `client_id` and a `client_secret`, to be used with `/oauth/authorize` and `/oauth/token`. It also, seemingly, requires returning an `id` with unclear purpose. The `/oauth/token` endpoint doesn't currently return a `me` field.
