mod_http_oauth2: Add TODO about disabling password grant
Per recommendation in draft-ietf-oauth-security-topics-23 it should at
the very least be disabled by default.
However since this is used by the Snikket web portal some care needs to
be taken not to break this, unless it's already broken by other changes
to this module.
