docker/unified: publish rootless image variant (#630)

Keep request duration from being underreported when upstream timings
only cover part of the full request lifecycle.

- compare wall-clock and upstream timing durations
- keep token and throughput values from timings
- add regression coverage for underreported timings

fixes #602

 - Use `make test-dev` after running new tests for a quick over all test run. This runs `go test` and `staticcheck`. Fix any static checking errors. Use this only when changes are made to any code under the `proxy/` directory
 - Use `make test-all` before completing work. This includes long running concurrency tests.
