    Support for scheduler hints for VM groups
    
    This is part of the blueprint vm-ensembles. The patch introduces the
    group as a scheduler hint.
    
    The patch set adds group support for multi-VM deployment. This is achieved
    as follows:
    1. A new hint is added: group. This will contain the name and type for the
       group. At the moment only anti-affinity is supported. In the future
       we will add network proximity. It will be extended to <name>:<type>
    2. In order to ensure that group policy will be honored for future VM
       deployments, the group is stored as system_metadata.
