Please describe your feature request

Hi,
I'am testing icinga-stack deployment to CERN kubernetes cluster air-gapped from the internet resources.
I wonder to what extent it is possible to adapt the Helm chart to allow configuration of the image source, particularly with regard to the resources of the internal-databases (mariadb) and redis templates. Alternatively, is there already a solution that allows me to specify my own paths?

used version 0.7.0: GitHub - Icinga/helm-charts: Kubernetes Helm charts to deploy a ready-to-use Icinga monitoring stack.

If I personally contribute to this feature, how long would it take approximately for it to be available?

DONE: update to internal-database and redis templates: to provide specific image path from the values
IN-PROGRESS: support for NFS volumes
