Special notes for your reviewer:

This PR is aimed at ensuring that customers can always set resource values. It adds a passthrough for the init container to inherit the same limits as the collector that is booted after it runs. I've also added empty resource config blocks for the kube-state-metrics sub-chart as in-line documentation to let user's know that this is one of the config options available to be passed to the kube state metrics chart.

Not only is it just good practise to ensure our customers have easy access to these settings, but It's especially important for GKE Autopilot users who get warnings and default limits set on them if they are not set manually. Which is what drove this effort, so I've also added a callout in the readme for that.
