vnf package upload failed with CSAR without policies

[Niraj Singh]

vnf package upload failed with error "InvalidCSAR: 'NoneType' object is not iterable" if csar file does not contain policies.

Steps to reproduce:

1) create a csar file without policies. It should only contain VDU's information

2) create one vnf package using below command:

openstack vnf package create

3) upload vnf package using file with below command:

openstack vnf package upload <package_uuid> --path <csar file path>

Expected result:

vnf package upload successfully

Actual result:

InvalidCSAR: 'NoneType' object is not iterable
