Ingress status update fixes

[specialforest]

• Updates samples with required permissions and ingress controller options.
• Adds code documentation for required options.
• Fixes case when the ingress controller updates statuses of ingresses not belonging to the controller.

This should address #2018. Also refactors changes from #1953 to avoid future errors.

Dockerfiles Build failed with unrelated error:

Is there a way to re-run checks without making a dummy commit?
