Public bug reported:

Suspending instance will not update resource usage.

Instance suspending should move all contents in the ram to hard disk.
Then vcpu and used memory should be decreased and hard disk useage should be increased.
However it didn't happen.

This will lead to trouble in the following scenario:
When the memory of all compute nodes are exhaust, to create a new instance, it's useless to suspend some alive instances, but have to delete them.
