Description of problem:
The <snapshot> XML that you receive from the API is currently looks like:

<snapshot href="/api/vms/086b5092-71d6-4cfa-b73d-d32bff2890cb/snapshots/93d8fc6e-bdcf-4726-b1c5-8c5c24f8a783" id="93d8fc6e-bdcf-4726-b1c5-8c5c24f8a783">
  <description>1</description>
  <type>regular</type>
  <vm id="086b5092-71d6-4cfa-b73d-d32bff2890cb">
     <name>elad2-3</name>
     <description/>
     <link href="/api/vms/086b5092-71d6-4cfa-b73d-d32bff2890cb/snapshots/93d8fc6e-bdcf-4726-b1c5-8c5c24f8a783/cdroms" rel="cdroms"/>
     <link href="/api/vms/086b5092-71d6-4cfa-b73d-d32bff2890cb/snapshots/93d8fc6e-bdcf-4726-b1c5-8c5c24f8a783/disks" rel="disks"/>
     <link href="/api/vms/086b5092-71d6-4cfa-b73d-d32bff2890cb/snapshots/93d8fc6e-bdcf-4726-b1c5-8c5c24f8a783/nics" rel="nics"/>
     <type>server</type>
     ... *more stuff not relevant for this bug*
  </vm>
</snapshot>

The links points directly with the URL to the collections (i.e. cdroms, disks, nics) being under the snapshot object, which is not consistence with the xml object which is <snapshot>....<vm><link ....=/collection/></vm></snapshot>.


Version-Release number of selected component (if applicable):
rhevm-3.4.0-0.3.master.el6ev.noarch
rhevm-restapi-3.4.0-0.3.master.el6ev.noarch

How reproducible:
100%

Steps to Reproduce:
1. Create a snapshot of vm with disk
2. from REST api go to: /api/vms/<vm_id>/snapshots/<snapshot_id>/
3. The links are located under <vm> ... </vm>

Actual results:
The links are found under vm: <snapshot>....<vm><link ....=/collection/></vm></snapshot>.
And a link to disks collection (for example) is:
<link href="/api/vms/086b5092-71d6-4cfa-b73d-d32bff2890cb/snapshots/93d8fc6e-bdcf-4726-b1c5-8c5c24f8a783/disks" rel="disks"/>
which is not consistence with the xml object

Expected results:
All links should be directly under snapshot and not under vm
