Code Issues Proposed changes

Snapshots/backups can no longer happen simultaneously. Tests included.

Browse Source 
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
