We currently have the test-setup.sh script that installs and configures the services that are needed to run the zuul test suite. However this needs mysql, postgres and zookeeper installed into the system. It also messes with tmpfs mounts of zookeeper. This adds a docker-compose based test setup that can ease the setup of the test requirements on a developer machine. Change-Id: Ib0e3f42898c6e9258625b03bcc363e91f4b7ee83
