KVM: add the template UUID info in the domain XML

[slavkap]

This could be used when you want to import an unmanaged VM and the user doesn't remember from which template the VM was created. It could be added as an entry in the sysinfo tag:
current state:

  <sysinfo type='smbios'>
    <system>
      <entry name='manufacturer'>Apache Software Foundation</entry>
      <entry name='product'>CloudStack KVM Hypervisor</entry>
      <entry name='uuid'>9f9d39da-e243-473a-b21d-3e31ea2d1cb1</entry>
    </system>
  </sysinfo>

with the template UUID

  <sysinfo type='smbios'>
    <system>
      <entry name='manufacturer'>Apache Software Foundation</entry>
      <entry name='product'>CloudStack KVM Hypervisor</entry>
      <entry name='uuid'>9f9d39da-e243-473a-b21d-3e31ea2d1cb1</entry>
     <entry name='template'>[UUID]</entry>
    </system>
  </sysinfo>

This will be in case the template isn't deleted from CS

@slavkap , I don't see template uuid mentioned in that feature request so you might want to add a comment there.
