Update QUIC transport parameters to draft 20
This CL updates from draft-18 to draft-19/20. The only changes are idle_timeout being in milliseconds instead of seconds, and the removal of the versions before the parameters. We've kept the versions in a custom Google-specific extension for now. This extension will eventually evolve into the IETF compatible version negotiation extension.
