### What would you like to be added? After receiving the instructions on how to setup a kubernetes test harness on Antithesis, we should do the following: - Add a separate setup for Kubernetes in Antithesis directory. - Confirm that etcd-operator works (i.e. can be used to setup the etcd test cluster). - Document the instructions how to setup the etcd cluster on Kind. - Antithesis has local validator for Kubernetes, so we should find a way to integrate with it and then document. cc @serathius @marcus-hodgson-antithesis ### Why is this needed? Next steps for Antithesis tests.
