clashing with Workhorse.

Changelog: changed

It turns out we cannot use moving refs like branch
names in our release tooling. Setting this to a SHA
should allow us to re-add GME to our release pipeline
without failing deploys.

This change:

- Adds a rake task to install gitlab-metrics-exporter
  into a given directory.
- Allows to run it in place of the existing Ruby based
  exporters; this is guarded by an environment variable.
- Extends the existing end-to-end test to test both
  Ruby and Go implementations.
