I'm skeptical about this, as:
* NO_TICKETS doesn't disable all resumption in TLS 1.2 (session ID based resumption cannot be turned off)
* resumption requires special API calls (e.g., `gnutls_session_set_data`); if the client program doesn't want resumption, it can simply skip those calls
That said, if we add a middle ground for compatibility, it would be an option to explicitly disable non-forward-secret session tickets; maybe NO_TICKETS_TLS12?
