Add s390x support to docker hub images

Docker hub SonarQube image currently supports only x86 arch. Will it be possible to add s390x images as well?
I see Dockerfile already has s390x support: https://github.com/SonarSource/docker-sonarqube/blob/master/8/community/Dockerfile

As far as i know, there is no plan to support such processor instruction set on our docker images.

Feel free to reuse our open-source Dockerfile and adapt them to your needs.
