Compute Driver Events
This provides infrastructure for compute drivers to emit asynchronous events to report on important changes to the state of virtual machine instances. The compute manager will be adapted to make use of these events, as an alternative to running a periodic task to reconcile events. The libvirt driver is enhanced to emit such events. The result is that Nova will immediately see when any virtual instance is stopped, instead of suffering (upto) a 10 minute delay.
