Support for prometheusRule

[reefland]

Details

I would like the common chart to be able to support prometheusRule, which goes nicely with the existing serviceMonitor.

Example:

# -- Enable and configure Prometheus Rules for the chart under this key.
prometheusRule:
  enabled: true
  labels: {}
  # -- Configure additionial rules for the chart under this key.
  rules:
    - alert: SonarrDown
      annotations:
      description: Sonarr service is down.
      summary: Sonarr is down.
      expr: |
        sonarr_system_status == 0
        for: 5m
        labels:
          severity: critical

Hi! Thanks for the feature request! I will add this to the rewrite that I am working on. Unfortunately time has not been on my side so progress has been a bit slower than I'd hoped.

I wonder if it's better to allow for this https://github.com/bjw-s/helm-charts/issues/314 ?

Not sure if it helps but I had intended to PR this back and just never got around to it
