Comment 1 for bug 1749394

In Tacker, I have created a VNFD with with autoscaling, template as in [1].

After that while deploying VNF with that VNFD, it failed with error:

vagrant@control:/opt/stack/tacker/samples/tosca-templates/vnfd$ tacker vnf-create --vnfd-id 221dc02a-1a87-4b8e-b782-c8fd8f3c3976 test
heat-translator failed: - [Errno 13] Permission denied: 'SP1_res.yaml'

As per my observation, root cause is [2] opening file in root dir (i.e. '/'), due to which it giving permission denied.
