<!-- What do you want to happen? -->

Sometimes, accessories to the installation may be manifests to be installed (for example, NetworkPolicies or Ingresses).

It would be nice to be able to do this directly via the Chart using the approach that [Grafana](https://github.com/grafana/helm-charts/blob/grafana-7.3.10/charts/grafana/values.yaml#L1302-L1311), [Prometheus](https://github.com/prometheus-community/helm-charts/blob/prometheus-25.20.1/charts/prometheus/values.yaml#L1208-L1216) or [OAuth2 Proxy](https://github.com/oauth2-proxy/manifests/blob/oauth2-proxy-7.5.4/helm/oauth2-proxy/values.yaml#L439-L466) also uses.
