Motivation: Http2MultiplexCodec doesn't currently have an API for using the response of a h2c upgrade request. Modifications: Add a new API to the Http2MultiplexCodecBuilder which allows for setting an upgrade handler and wire it into the Http2MultiplexCodec implementation. Result: When using the Http2MultiplexCodec with h2c upgrades the upgrade handler will get added to the Http2StreamChannel which represents the half-closed (local) response of stream 1. It is then up to the user to manage the transition from the IO channel pipeline configuration necessary for making the h2c upgrade request to a form where it can read the response from the new stream channel. Fixes #7947.
