Abort the script and trigger the clean up script, whenever any of the
commands below to prepare the testsuite are failing. This saves time
with figuring out why suddenly all or most tests are failing, and avoids
running the entire testsuite on jenkins if it's obviously not going to
work.

Add set_clean_up_trap() in jenkins-common.sh and run it at the beginning
of the jenkins.sh files. Move the common clean up code from the end of
every jenkins.sh file into clean_up_common(), which gets called by the
trap. Add a custom clean_up() function to those jenkins.sh files that
need additional clean up.
Replace explicit container stop commands (for containers attached to the
docker network) with one call to network_clean() in clean_up_common(). It
kills all containers attached to the docker network.
The motivation for this change is the upcoming optional build of initrd
and kernel during ttcn3-ggsn-test/jenkins.sh. After building these, a
short smoke test will be performed to make sure we can boot the kernel
and initrd, before continuing to run the entire testsuite against it. If
building or the smoke test fails, we must do a proper clean up of the
network and fix permissions.
