Backport of NET-5530 Support response header modifiers on http-route config entry into release/1.16.x (#18725) 

* NET-5530 Support response header modifiers on http-route config entry (#18646)

* Add response header filters to http-route config entry definitions

* Map response header filters from config entry when constructing route destination

* Support response header modifiers at the service level as well

* Update protobuf definitions

* Update existing unit tests

* Add response filters to route consolidation logic

* Make existing unit tests more robust

* Add missing docstring

* Add changelog entry

* Add response filter modifiers to existing integration test

* Add more robust testing for response header modifiers in the discovery chain

* Add more robust testing for request header modifiers in the discovery chain

* Modify test to verify that service filter modifiers take precedence over rule filter modifiers

* Generate deep-copy code
