I was following the release demo video for v2024.01.0
https://www.youtube.com/watch?v=PNwMkenQQ24 and when I did 'docker
compose up' the containers couldn't resolve the DNS name for 'zookeeper'
I realized this was because the zookeeper container was using the
default docker network, so I specified the wmsa network explicitly.
This adds a single-node barebones configuration to the install script. It also moves the log4j configuration into system.properties, and sets assertions to disabled by default.
