To avoid running into an issue in the race unit test with the Prometheus histogram metrics that aren't concurrency safe, we don't register any of them if Prometheus isn't enabled in the first place. This shouldn't be an issue in production, since we don't start multiple instances of Aperture _within the same process_ at the same time.
There's a race condition in the h2_bundle.go of go 1.16.10 and later. The issue golang/go#51799 mentions that this might be fixed in go 1.19, so we'll need to wait for that. We make sure we build our docker images with go 1.16.9 to not run into the issue in the wild.

Fixes #71.
Turns out the problem was the histogram metrics for Prometheus added recently. They aren't concurrency safe. Since we don't start multiple instances of Aperture within the same process in production, we should never hit that outside of race unit tests.
We also move over to GitHub Actions because Travis sucks.
