Expose duration and latency metrics as response headers #7879

Is your feature request related to a problem? Please describe.

I would like to be able to add request, response, and upstream latency/duration to response headers. Specifically:

From the latency filter:

%DYNAMIC_METADATA(io.solo.filters.http.proxy_latency:request_out)%
%DYNAMIC_METADATA(io.solo.filters.http.proxy_latency:request_out_internal)%
%DYNAMIC_METADATA(io.solo.filters.http.proxy_latency:request_out_internal)%

From the access log operators:

%DURATION%
%REQUEST_DURATION%
%RESPONSE_DURATION%

Have tested using clusterMetadata in an Inja transform but this does not expose the required data

Describe the solution you'd like

Be able to configure response headers to include the metrics above, probably via a response transformation

Describe alternatives you've considered

None

Additional Context

No response
