Start zookeeper with users uid in test-setup-docker.sh

The zookeeper containers entrypoint will try to switch to the user
'zookeeper' if the container is started with uid '0'. This can cause issues
when the uid for the zookeeper user inside the container and the
users uid outside the container differ since it will lead to zookeeper
getting access denied when trying to read the certificates.

This also adds logging configuration to make it easier to debug
zookeeper in the future.
