Here are my plans for -02
* websockets parameters (sub-protocol, etc..) into h2 HEADERS
* define the websockets target URI scheme for CONNECT as being http/https
when using 6455. I actually think this is a change from 6455 but I can live
with it if its defined. Mostly the concern is around legacy pac.
* stick with CONNECT as the method for the moment.. my thinking here is
that CONNECT is already a strange beast with special code doing almost what
we want here anyhow.. replicating that is not great. I would rather have a
pseudo header be the version specific thing (which is expected of pseudo
headers) than adding a new method which is typically not.
