1301 parametrize image locations

[danielpodwysocki]

SUMMARY

This allows users of private registries to use Values.yml to configure the operator and rbac proxy images and point at their images, while keeping the default behaviour same as on the current chart.

It removes the need to constantly rebuild the chart in-house and makes it reusable across organizations.

It also includes a separate commit with a minor yq fix - a missing -y flag was causing it to error when testing the helm-chart make target.

For registries requiring authentication, this also needs a method to define imagePullSecrets.

I will update this PR when I get a moment to sort that.
