Automatically add the required pre-delete hooks for referenced required secrets

[ulucinar]

What problem are you facing?

Looks like we have example manifests in which we do not protect a referenced required secret (which supplies the value of a required sensitive argument) so that it's only deleted after the referring resource. We may or may not be able to catch this with an uptest run.

How could Uptest help solve your problem?

We may implement a linter that checks this. Another option could be to implement a preprocessor (which we are considering to handle reference injection from a common library of dependencies), which can also inject referenced secrets together with the required hooks to order deletions.
