Fix cockroachdb statefulset test read/write commands

Explicitly specifying `--insecure` is required on insecure clusters,
which started being enforced in a very recent release. In 2 weeks
we'll have a stable image version that we can reliably pin the
relevant statefulset yaml file to in order to avoid stupid failures
like this. I'm really sorry for the flakes!
