TODO
Use bin/helios and bin/helios-master to start the Helios CLI and server
(respectively) from the locally-built project.
If you are running helios-system-tests locally and are wondering where the
slf4j/logback output is when the tests are being run, SystemTestBase will by
default configure logback to be extra verbose and to write
logs to /tmp/helios-test/log/.
This behavior can be disabled by disabling the logToFile system property when
maven-surefire-plugin is invoked.
