CI: move kubeval validations prior to deployment in review/stable stages
Summary
Currently, we have have 2 validation jobs that make use of kubeval. These happen in the package
stage, as well as the lint
job.
I believe it makes sense to move these to before review
/ stable
stages, so that we've ensuring fully valid output prior to attempting to actually deploy any modifications to these charts into CI.
We also have lint_package
in that step, but perhaps we should re-arrange it as well?
