Description of problem:

since snapshot is on entire vm and not just the disks, and we cancelled the image lock on vm during snapshot we should add a CanDoAction on add disk while disk images are locked due to snapshot to prevent possible races which will cause image corruption. 

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


How reproducible:


Steps to Reproduce:
1. create a snapshot
2. create a new disk
Actual results:

vm is not locked only disk images and there is no CanDoAction -> new disk will be created while a snapshot is taken. 

Expected results:

we should add CanDoAction to add disk if the disk images are locked due to snapshot.
