Refactor the ownership model of FM so that it can be composed more easily: by moving all ownership of headers to the HCM, nested FM can pass ownership all the way up. This simplifies ownership transfer complexities that arise when the FM attempts to own the headers. Signed-off-by: Snow Pettersen <snowp@lyft.com>

This is still far from complete but now passes test/integration:protocol_integration_test so at least its in somewhat the right shape. I'll start splitting out parts of this PR that makes sense so that it all can be reviewed independently. |

Just a thought, but once this stabilizes, could the changes to router land on their own, and we could copy-paste-clone the upstream request and runtime guard for a month or two? It is as you say a pretty high risk change. |

Yeah I think that would be prudent, this introduces a whole lot of new code into the upstream request flow, so hard to know what might break. |

This refactors the UpstreamRequest to use FilterManager with a UpstreamRequestFilter to manage the upstream stream. This will open up for eventually supporting upstream filters that can process the upstream request/response.
