This adds a basic JWT check to the /dispense/github-runner-token endpoint.
It also adds a basic auth server endpoint for OAuth 2.0 Client Credentials grant type authentication to serve JWT tokens signed with a symmetric secret (since the Client Credentials flow is the most suitable and Dex doesn't provide this flow).
