Implemented exception.InstanceBusy when attempting to snapshot/backup an instance which is already snapshotting or being currently backed up. Fixes bug 727502. (Patch Set 2) 3 new exceptions: InstanceBusy, InstanceSnapshotting, and InstanceBackingUp (Patch Set 3) Oops. New exceptions now inherit from InstanceBusy (Patch Set 4) Tests now tear down created instances Change-Id: I9614740bba26c04e64b0e27c24fbace12334f4d1
