  - Remove cleanup from play-resources
    
    When play-resources does not use
    bindmounting, there is no need to manually clean up resource files.
    That makes it possible to remove cleanup.yml all together.
    This is in preparation to remove the othervise unneeded
    cleanup-directories role.
