Multiple requests can use the same client_state simultaneously, so it is
not safe to use it as a container for a tracing state which is per
request. This is not yet an issue for the alternator since it creates
new client_state object for each request, but first of all it should not
and second trace state will be dropped from the client_state, by later
patch.
