Partial string matching on resource values?

What would you like to be added:
I found it pretty surprising that I couldn't do partial string matching (regex or wildcard) on the values in created resources.
Why is this needed:
When working with custom resources like XRDs in Crossplane, I find it difficult to validate certain kinds of dynamic resources because they fundamentally change the return values.. for example, verifying that my Role resource has a status.roleArn field that matches arn:aws:iam:.... The role ARN changes on every test, but fundamentally my goal is to verify that a value was put in there and that it's not empty.
The closest thing possible right now is to use a TestAssert with a command that does some kind of templating/substitution (if the value you're looking for is predictable at all) and runs a nested kuttl assert.
#387 might make this easier but there are no plans to support regexes. You might want to take a look at https://github.com/kyverno/chainsaw
Thanks @porridge for the mention!
https://github.com/kyverno/chainsaw supports wildcard matching (and regexes too).
