Introduce a new stateful session extension. This is a change after #17848#17290.
In #17290, we added a new cross-priority host map for fast host searching. In #17848, we extend `LoadBalancerContext` interface to provide an override host and to select the upstream host by the override host.
Finally, in this change, we expand a new API to allow users to extract the state of the session from the request and change the result of load balancing by setting the override host value.

This is a follow-up to:
#14432 (comment)
After that PR, it's no longer possible (unless you do a dynamic_cast)
to set the remote address from a filter. This is something that we
need to do because we have specialized logic for this (XFF doesn't
work for us).
So this adds an extension point which will allow us to push that logic
down to ConnectionManagerUtility::mutateRequestHeaders() where it
belongs.
