Description of problem:

User should be able to create a vm from some template and amend some configurations if he likes. In particular user should able to create a stateless vm based on 'latest' template version so the vm can update according to template versions. Right now due to the change introduced in bz#1293154 this cannot be achieved if the latest template is not configured as stateless itself.
While this is not a major issue and can be rather easily WA by editing the template, this should be changed so that when a user chooses 'stateless' on the create vm menu and then some latest template is chosen, it will not override the stateless configuration.

Version-Release number of selected component (if applicable):
rhevm-3.6.5.1-0.1.el6.noarch

How reproducible:
always

Steps to Reproduce:
1. Create template from some statefull vm.
2. Attempt to create a new vm -> set stateless check-box. 
3. In Create vm->general menu choose the template you created as 'latest' version in the template drop down.

Actual results:
Vm inherits template's configuration and set back to statefull, vm's template is set to base template version (1).

Expected results:
Vm inherits should inherit template's configuration except for the stateless, allowing to create the vm as stateless, with latest template version, regardless to the template statefullness.
