Configure resources for all containers

[paymog]

It would be great if this chart either directly configured resources for the rbac proxy container or allowed consumers of the chart to manually specify resources. Additionally, it would be great of both pods had requests and limits for ephemeral-storage which is a resource as of 1.25. I'm finding that often my nodes get killed because the rbac proxy pod uses up more storage than it requests (with a request of 0) and this causes the node as a whole to run out of storage and cause all pods on the node to suddenly get evicted.

Thanks for surfacing this, @paymog! I'll surface this with the team and follow up here with updates.
