docker.service and docker-storage-setup.service services failed to start at fedora-21-atomic-5

adding '--storage-driver devicemapper' to /etc/sysconfig/docker-storage, will fix the problem with docker.service.

    Increase size of Docker volume size

    Add logs for docker and docker-storage-setup services.
    docker-storage-setup uses MIN_DATA_SIZE=2G for Docker volume, so we
    cannot use Docker volume less that 2G (realistic 3G, because some
    space should be allocatedtd for medata-data)
