Support custom status checking for composite resources

### What problem are you facing?

Certain resources (eg. storage class, volume snapshot class, other custom CRD resource types) don't have `type: Ready`, `status: True` in their status, cause `function-auto-ready` reporting them as `not yet ready` even when they have been created successfully.

### How could this Function help solve your problem?

It would be helpful if there's a way to configure what status message or specific field to look for status update.
