Add WaitContainerReady for wait for docker registry ready

Sometime podman push local registry still failed caused by the
docker registry is not start yet after sleep 5s in the test.
So add this function to check the container status by its output
and skip the test when the docker registry can not start normally
instead of failed the case.
