Title: add lifecycle callbacks Entities and Biz objects

EntityBiz invokes onAdd, onUpdate, and onDelete methods to inform
subclasses that a lifecycle action is taking place on a domain object.

VroomEntity invokes onCreate, onUpdate, and onDelete methods to inform
subclasses that a lifecycle action is taking place on a domain object.

VroomEntity also invokes onSaveDao and onDeleteDao to inform subclasses
that a lifecycle action is taking place on a DAO.
