    mark a few oidc parameters as required

    to better the user experience, mark a few of the open id connect
    options as required, users should get back more meaningful
    error messages.

    as part of the change, there was also a discrepancy between what
    the loader used for the authorization code, and what the plugin
    was using. deprecate the old loader option (authorization-code)
    in favor of the one used by the plugin (code).
