Description of problem:

currently when I create a template from a vm with thin provision disk we calculate the preallocated space of the disk for the quota. 
since the template's images are locked and we cannot write to it we should calculate the actual size and not the vsize. 

Version-Release number of selected component (if applicable):

si13.3

How reproducible:

100%

Steps to Reproduce:
1. create a 30GB quota and a vm with 20GB thin provision disk (actual size should be 1GB)
2. create a template
3.
  
Actual results:

we are failing on insufficient resources from quota

Expected results:

we should not fail since the template images are locked and we cannot write on them -> hence we should calculate actual size and not vsize for templates.
