    Support for scheduler hints for VM groups
    
    This is part of the blueprint vm-ensembles. The patch introduces the
    group_name and the group_policy.
    
    The patch set adds group support for multi-VM deployment. This is achieved
    as follows:
    1. Two new scheduler hints are added:
        i.  group_name - a name for a VM group
        ii. group_policy - the deployment policy for the VM group. At the moment
            'anti-affinity' is supported and in the future we will add network
            proximity.
    2. In order to ensure that group policy will be honored for future VM
       deployments, the group_name and group_policy are stored as metadata.
