  Added github actions
  
  Just for record for "act" for local testing. To run with podman based distros, several steps are ncessary. See https://github.com/nektos/act/issues/303 ; especially
   * https://github.com/nektos/act/issues/303#issuecomment-937698375
   *  and https://github.com/nektos/act/issues/303#issuecomment-962403508
      *   the bind and socket
  eg:
   systemctl enable --now --user podman.socket
   systemctl start --user podman.socket
   export DOCKER_HOST=unix://$XDG_RUNTIME_DIR/podman/podman.sock
   ../act/bin/act   --bind --container-daemon-socket $XDG_RUNTIME_DIR/podman/podman.sock
  
   To rerun the build on clean env, you have to stop and start the podman socket again
  
  Without explicit 'mvn test' the tests are not running. Not sure why
