Add UTs to plugins
Deployment, service and namespace are plugins which offers CRUD operations to manage their resources. They haven't implemented Unit Tests which makes fragile to change/refactor the source code. This change adds their corresponding Unit Tests and defines a standard interface. Change-Id: I1e1eb40f1a18ba33c74069a117462c8df17767ac Signed-off-by: Victor Morales <victor.morales@intel.com> Issue-ID: MULTICLOUD-301
