Subject: Add vnf definition APIs

Adding APIs for POST, GET, LIST (implemented via GET)
and DELETE commands on /v1/vnfd base for creating,
getting, listing and deleting VNF Definitions.
P2: Added unit tests for vnfdhandler.go
P3: Add unit tests for serialize and deserialize
P4: Integrating review comments
P5: Added customizable mocking for vnfdhandler_test
P6: Added customizablt mocking for vnfd_test
    Note that this will soon need to be updated once
    the db changes go through in patch 71090

Issue-ID: MULTICLOUD-393
