Traefik middleware for dealing with authentication and redirecting

[einari]

Look into supporting cookies and bearer tokens.
Verify tokens with the auth provider using the JWTS - RSA keys.

This is related to the Sentry project - we need to discuss how we do this practically. Sentry is moving towards a place where it will have the configuration files mounted as a volume. We need to see how we will deal with the configuration data that Sentry provides for this.

If they share the files, we need to deploy a new Traefik controller if we do changes to the format in main Sentry - not ideal. We could look at doing integration on file level now and then set up a separate task for later to make this get the events from our Event Horizon.
