feat(marketplace): pre-delete resource check and post-delete complete uninstall

[vdice]

• Adds a pre-delete helm hook to check if any SpinApp or SpinAppExecutor custom resources exist in the cluster; if so, fail the hook and thus the deletion attempt
  • Note: the top-level helm delete command will time out and the error will only be seen if the user procures the logs from the 'pre-delete' job pod(s). In the context of the Marketplace, this might not make its way to an 'extension failed to uninstall' error; unsure here.
• Adds a post-delete helm hook to remove all SpinKube CRDs (at time of writing, these include the Cert-Manager dependency CRDs as well as the SpinApp(Executor) CRDs).
  • Note: The hook also deletes the release namespace as a final step, since helm does not do this.
• Updates the helm smoke test GH workflow with assertions for the above logic

Perhaps add kubectl describe as well?

Thanks!

Oops, CI happened to hit a cpa verify error. I created #31 to fix. We can merge 31 first and I can rebase this afterwards.
