What this PR does / why we need it:
While using the Gator CLI (v3.9.0) to test helm rendered k8s resources against our Gatekeeper constraints we ran into the following error:
auditing objects: adding data of GVK "/, Kind=": admission.k8s.gatekeeper.sh: invalid request object: resource has no version
After investigation we found out that the error was due to a input file like the following one:
Apparently Gator CLI attempts to parse above snippet as 3 seperate YAML documents, looking for k8s resources inside them, which won't work as the second one containing only the comment cannot be parsed into a valid k8s resource at all.
This PR suggests skipping empty k8s resources.
