Ingress as configurable option within chart itself

Similar to how other charts handle Ingress as a configurable option via ingress.enabled: true/false, it would be operationally helpful if the helm deployment of Stratos had Ingress as a configuration option included in the chart rather than requiring it to be configured/added on as an external file

Context p1: my personal use-case

As a proof of concept I installed SUSE/scf (CF on k8s) as a helm chart & leveraged an Ingress rather than multiple Service: LoadBalancer's. I wanted to leverage Stratos for the UI using the cluster-wide Ingress Controller rather than setting up new DNS entries for the LoadBalancer services that would get generated. I thought about installing Stratos as an app on CF Docker app instead, but sadly I don't think it's possible to run docker images on the k8s CF deployment model yet.

Context, p2: general use-case

When deploying helm charts, either manually with the helm-cli or with a declarative helm tool like helmfile, it's beneficial to have the deployments be as declarative as possible. Any steps required outside of what can be defined statically makes the deployment "snowflake-y" (hate that term, but whatever).

In order to use an Ingress I need to go manually download the ingress.yml, which breaks the workflow of:

helm repo add stratos https://cloudfoundry-incubator.github.io/stratos
helm repo update

# setup a stratos-values.yml with all the options you want enabled, including Stratos version + Ingress config and such...

helm upgrade stratos/console --install --namespace=console --name my-console --values stratos-values.yml

and means people need to add in manual steps, like maybe having to wget https://github.com/cloudfoundry-incubator/stratos/blob/v2-master/deploy/kubernetes/ingress/ingress.yml or something. And even then, since it's not part of the versioned Chart.yml, there's no guarantee that it'll work with the version of Stratos you're using.

Possible Implementation

Stealing from drawing inspiration from other helm charts on how they do Ingress? e.g. like Concourse or minio or artifactory, etc. I'm by no means a helm expert, so I apologize for opening an issue rather than a PR with the suggested improvement. I can take a crack at it, but someone smarter than I + w/ more context might be more appropriate.

Thoughts?

Thanks for your time & consideration 👍
