I think it would be good if the distinction between dst_logical and dst_concrete was documented in the code where they appear, if possible.

When I tested this, it worked as expected when I queried Prometheus for outbound requests while I had a trafficsplit running. 👍 |

lgtm.. before merging, though, can you confirm whether any of the (flakey) metrics tests need to be updated with the new metrics?

Supersedes #296
The authority label reflects the concrete dst of the request in the endpoint stack. In the case of a traffic split, this may be different from the actual authority of the request (i.e. the logical dst).
We add the logical dst as a field on the endpoint target and use this value for the authority label instead of the concrete dst.
The net result is that the authority field reflects the apex service of a traffic split and the
dst_servicelabel reflects the leaf service.E.g.:
