    tier/shd: create shd volfile for tiering
    
    Currently shd graph will only start if it is replicate
    or disperse volume. But in case of tiering, volume type
    will be tier. So we need to start shd if any of the cold
    or hot is compatible with shd volume.

    tier/shd: make shd commands compatible with tiering
    
    tiering volfiles may contain afr and disperse together
    or multiple time based on configuration. And the
    informations for those configurations are stored in
    tier_info. So most of the volgen code generation
    need to be changed to make compatible with it.
