Currently not tested, as most of must_gather scripts.

Requires a Prometheus around.
Let's have a test for it in origin, via CMO's OTE https://github.com/openshift/cluster-monitoring-operator/pull/2616

This will help guard the behavior/API against changes like https://github.com/openshift/must-gather/pull/489, which breaks the script (I'll reach out to them)

maybe have it run alongside https://github.com/ardaguclu/origin/blob/main/test/extended/cli/mustgather.go
