Build osmo-*-master docker containers with address sanitizer
In order to catch use-after-free and similar bugs during TTCN-3 test execution, it would be great if we'd modify the
docker-playground/osmo-*-master containers to build with asan enabled. We'd of course have to capture the stderr output of the related processes somehow into jenkins (e.g. as artefacts) to reap the benefits from this.
