Packer building pipeline for QE infra

SInce we are using openstack environment with multiple configurations for our products - Strimzi, AMQ STreams on OCP, AMQ Streams on RHEL, with jdk8 and jdk11 we have to have some kind of automation for building base images for VMs. For this purpose Jiri Danek from MSG QE created packer pipeline for clients and broker team. Me and David from enmaase we updated his approach and created ansible role for proper provison of our images.
