Description

Currently, both lager and goldrush are being started by default, but the tests will run without explicitly starting them. Removing them also makes it possible to use this code downstream, where lager is not necessarily a dependency.

Finally, the same applications which are started by default should also be stopped by default. Currently, those are different lists of applications.
