  - Merge "vm workload consolidation: use actual host metrics"
  - vm workload consolidation: use actual host metrics
    
    The "vm workload consolidation" strategy is summing up instance
    usage in order to estimate host usage.
    
    The problem is that some infrastructure services (e.g. OVS or Ceph
    clients) may also use a significant amount of resources, which
    would be ignored. This can impact Watcher's ability to detect
    overloaded nodes and correctly rebalance the workload.
    
    This commit will use the host metrics, if available. The proposed
    implementation uses the maximum value between the host metric
    and the sum of the instance metrics.
    
    Note that we're holding a dict of host metric deltas in order to
    account for planned migrations.
