Motivation

The generated dnsNames configuration on certificates is incorrect for fully qualified names. It generates *.<release>-<component>.namespace.svc.local rather than <release>-<component>.namespace.svc.local

I'm assuming that a wildcard certificate should also exist so that TLS hostname verification works when connections are made to a pod in a headless service used for either the broker or zookeeper STS. Please adds CI tests to cover possible gaps.

[smbecker]

When I tested this locally, the wildcard does not allow me to hit the service using the fully-qualified name. Only removing the wildcard allows the fully-qualified name to work.

I updated the ci tests to use the fully qualified name when testing producer/consumer. Is that sufficient?
