Readiness check for sentinel shall fail when it doesn't monitor the right master, at least when we know that it monitors the wrong one which is 127.0.0.1
There'll be dependency on grep and head existing on the redis image used for sentinels. I tested alpine and bullseye in the official redis images here and they worked as expected.
I think we should have customised readiness and liveness checks in the future as well but for now this should be enough.
