Make "Prometheus compatibility (:docker:)" test in buildkite pipeline runnable locally

[kentzeng12]

We fixed the "Prometheus compatability (:docker:)" test in buildkite pipeline, however this solution #4295 will not run on local developer machines. We need to make this test be able to run locally.

The test is found here: https://github.com/m3db/m3/blob/master/Makefile#L231

Currently it works when running inside a docker container, such as in the buildkite pipeline.
