Provide a new home for the helm chart

[mrueg]

Is this a BUG REPORT or FEATURE REQUEST?:

/kind feature

What happened:
https://github.com/helm/charts#deprecation-timeline helm/charts repository which currently hosts the kube-state-metrics chart will become obsolete in Nov 2020.
What you expected to happen:
Figure out a new place for the kube-state-metrics chart. Ideally, it could live in this repository as a directory (similar to the jsonnet mixin) and get published on helm hub.
Currently @tariq1890 and I are maintainers of the helm/charts chart and could maintain it here as well.

I am okay with adding the helm chart to this repository. Thoughts @brancz and @lilic ?

[brancz]

I'd be fine with that as well, ideally we could even generate it from the jsonnet code we have, but I wouldn't block it if it wasn't. The only think that I would be a bit strict about is that everything has to be equally automated as the jsonnet things we have, so that releasing a new version doesn't have any other steps than the current VERSION file bump.

[lilic]

Yes fine as well, not to familiar with Helm charts so don't think I can contribute much to it, but no objections.

[mrueg]

Would you be comfortable with a contrib/ folder structure that includes a charts subfolder? This could potentially include jsonnet and other deployment options as well. If we can generate a helm chart from jsonnet or at least synchronize it, that would be perfect. A goal would be to publish it via CI to https://hub.helm.sh/charts/stable/kube-state-metrics (stable namespace would be replaced with a different one)

[brancz]

That's effectively what we used to have, and that didn't work out well. I'm all for synchronizing the chart with jsonnet though regardless of where it's located! :)

I have started a draft PR for this: #1237

Looking for feedback on the to-do items I added, before I do too much more on this. Happy to finish after feedback 🙂
