Node Suspension and Power Saving
================================

Put allocated nodes that are not busy to sleep, to save power. Change power state of machines.

Options:
 * powernap
     - extend powernap to make it aware of the type of workload running on the machine (having charms populate /etc/powernap.d/)
 * on-demand suspend (or other power states) through MAAS API
  * IPMI control of power states (possible?)
 * Landscape to control on system
