I don't think this belongs here.   The default_protocol should only be used when
we are doing spdy over non-NPN.  I think we should add this option for
kDisableSSL, kSSL.  What do you think?

+1. Will test chrome when kEnableNpnHttpOnly, kDisableAltProtocols options are
enabled (to verify nothing is broken).
Done.
