Merge "Add UTs to plugins"

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.
