(Broken out of #3214.)

In Section 13.4 
>An endpoint
>   validates the use of ECN on the path, both during connection
>   establishment and when migrating to a new path (Section 9)./
- I think the QUIC endpoint MAY also validate ECN is still support by the path during communication. This may be necessary when ECN is enabled, but a path change results in there no longer being support.
- I think this needs to also be permitted in Section  13.4.2, allowing QUIC to suspend ECN usage for a path or to an endpoint for which it currently has a connection.
