1. Error message is not informative

+ echo '<failure type="Failure" message="failed">'
+ echo '<![CDATA['
+ tail -n 20 testing-openstack-ceilometer-common
+ echo ']]>'
+ echo '</failure>'

Further investigation led to "Cannot allocate memory" error.

Error is triggered by
https://review.fuel-infra.org/#/c/12209/81/tests/runtests.sh

As you could see there are a lot of running services inside this tests and this is a root cause.
I can't say for sure which number of bytes we need exactly.

2. Another problem is just incorrect runtests.sh - services should be killed after each step of test.

It could be great if we could have more informative logs and ideally output of runtests.sh.
