The Zeus config has been broken since integration tests for Rails engines were added. It appears that the Zeus boot step responsible for loading Combustion was passing an empty array for the modules to initialize. Outside of Zeus, the integration test customizes this array, but inside Zeus, that never happens, and there isn't a way to do that. So, considering that we only have one engine-specific integration test, I removed the customization option and hardcoded the list of modules, renaming the boot step and corresponding command to match. I then corrected the test accordingly.
