As per ETSI GS NFV-SOL 005 V2.4.1 (2018-02) table 9.4.2.3.2-2, GET Vnf
Packages should return list of all Vnf packages, but as per current
implemention this api is returning dictionory with resource name as key
i.e {'vnf_packages': [{vnf_package1}, {vnf_package2},...]}. Hence
removing the resource key and returning api response as a list.
As per process to fix this issue we need to provide micro version
support in tacker as well as in python-tackerclient for command.
The list api was part of VNF package api which released in train cycle.
But we can not instantiate, terminate and Heal VNF as these feature is
not released yet and about to release in U cycle. The changes we have
proposed will be useful after U release and that is why we think we
should do these change without micro version support.
