Set up metrics config stuff

Description

Helpers for standing up metrics collection. I've decided that SimKube itself isn't going to set up any service monitor or pod monitor collection, this needs to be done by the user, because there's just too many ways to configure it. SimKube will optionally stand up a Prometheus pod using the Prometheus operator that can point to a configurable set of service or pod monitor objects, but you can also now disable this entirely and set up your own metrics collection.

Testing done
