We previously prohibited connection-specific in HTTP/2, but we only really pointed at those listed in Connection.  As the core drafts list a set of other fields, it makes sense to reference that.

The core spec: https://httpwg.org/http-core/draft-ietf-httpbis-semantics-latest.html#field.connection
The pull request referencing that: https://github.com/httpwg/http2-spec/pull/946

The effect of this is a change.  This explicitly includes the fields listed (Proxy-Connection, Keep-Alive, TE, Transfer-Encoding, and Upgrade) as prohibited.  We already said that Transfer-Encoding was impossible, so this is consistent with that, but this could be a change.

Any objections or concerns?
