CLOUDSTACK-7194: deployVm Api, "hypervisor" parameter:
* is respected only when vm is deployed from ISO, or hypervisorType is not set on the template record
* if parameter passed when vm is deployed from template having hypervisor info set, validate that these 2 parameters are the same instead of silently defaulting the final value to the one set on the template
