Currently we exit the program if the setup does not work, this can cause
is to leave containers and other resources behind since we dont run
TearDown. This change will just fail the test if we cant set up, which
should mean that the TearDown runs aswell.
We currently have a bit of flaky logic which prevents the docker plugin
from cleaning up the containers if the tests or setup fatals or crashes,
this is due to a limitation in the save / passed stats handling.
This change makes it an environment variable which by default ditches
the logs and makes the containers clean up "correctly" in the teardown
method.
