It should be possible to disable the any/all PrometheusRules

Feature Request

Why

We have a multitenant architecture, where we don't control the development of our tenant's applications. As such, they are frequently in bad states in ways that we cannot address/fix, dropping 500 errors left and right. Such is the way of platform management, however there's one PrometheusRule that is blowing up our AlertManager:

https://repo1.dso.mil/big-bang/product/packages/monitoring/-/blob/main/chart/templates/bigbang/rules/istio-proxy-mem-prometheusrule.yaml#L37-44

As far as we can tell, it's impossible to disable any of the rules in these files. Can this please be configurable?

Proposed Solution

Make the bigbang/rules/* files configurable to disable.
