Use the Eirini helm chart instead of the BOSH release

Is your feature request related to a problem? Please describe.
We'd like to use Kubernetes-native components where available.

Describe the solution you'd like
Instead of converting the Eirini BOSH release through the CF Operator, use its helm chart.

What is the impact?
We wouldn't need to support the Eirini BOSH release anymore.

How to measure it?
Everything should work as before.

We have done the same as a "spike" and you can find the result here: https://github.com/akhinos/kubecf-external-eirini. There is a README.md with the changes we had to apply to make it work.

• Changes to kubecf, e.g. install bits but not eirini
• Changes to the eirini-release, e.g. make registry_address and registry_port configurable via helm
• Usage of shalm (https://github.com/kramerul/shalm) to install the helm charts (cf-operator, kubecf, eirini) to address dependencies, e.g. timing, secrets that have to be "smuggled", ...
