ci: Add a helm chart to test this image #98
Description
Per the title, this is to track adding a helm chart that will use this image in various ways to smoke test the image.
This can have a dual purpose of the test chart implementing the best-practices this repo documents for how to manage it. The reason this is relevant is because the rancher/kubectl image had a fairly standard way to implement it in a way where consistent global overrides could be used.
An example of this that is novel to kuberlr-kubectl would be: #60
This effort was originally started in this PR: #91
However the basic CI work was spun off to a new PR to merge that asap. This PR could be used as inspiration for or a foundation to complete this issue.
