* Create a culler as a package
Helper functions for culling resources. Takes for granted that ISTIO is
installed to the system and queries Prometheus to get metrics.
Specifically, requests/{configurable time}.
If the resource should be culled, then it should be done by setting an
annotation. This way the UIs can also show that the Resource is stopping
and also easily stop a resource by making a PATCH request.

* Culling logic enhancements
Add necessary ENV Vars. Culling won't happen by default. To enable it
the user will need to set the ENABLE_CULLING=true
