    Quotas by Volume Type
    
    The VolumeTypeQuotaEngine creates a volume, snapshot, and gigabyte
    quota for each volume type that exists, in addition to the existing
    global quotas for each. These are queried every time a quota operation
    happens.
    
    Add a table for storing quota default values. These values are used
    before values in the config file. This allows the user to add a volume
    type, and add a default quota for it with no downtime.
    
    The volume type quotas also can be defined in the config file under the
    keys:
    quota_volumes_<vtype>, quota_gigabytes_<vtype>, and
    quota_snapshots_<vtype>.
    
    Another patch will have changes to cinderclient for setting project
    quotas by volume type.
