SQL storage backend support

[alex-lx]

Helm supports SQL storage backend, it would be nice to support it in helm-controller, it would be useful especially when not able to create secret or configmap on kubernetes cluster. Here's a real situation we meet fluxcd/flux2#1473

This would perhaps also be useful in a not-hypothetical situation where someone is making hundreds or thousands of deployments and the number of secrets gets too large for helm (ok, kubernetes) to enumerate in a reasonable time. :)

Is there any plan of implementing this ? It would be a shame to have this work go to waste. We would very much appreciate this as we have chart approaching the limit.

And the solution you are considering is deploying a SQL DB to handle it?
