http2.js
protocols object to store defaults for http and https, and use as a switch for supported protocols.
options.hostname > options.host > 'localhost'
if I have an options.auth element and I do not have an Authorization header, I do basic auth.
http.request collapses to new ClientRequest since the defaults are handled by the protocol object
