[Openstack] Shrink Image's Flavor Requirements

 Let's assume that I have a VM's image that has been taken when the VM 
 was launched with a flavor of 50GB for the root disk.
 Now when I try to spawn a new VM out of that image I cannot do it with 
 a flavor that has disk less than 50GB even if the VM itself inside uses 
 only 5GB.

 Is there a way to shrink the image's flavor requirements?
