Title: db model can be updated, 

1. a new service to retrieve workspaces for a type of object (eg Milkbox) is added.

2. service get_object_on_tray implemented. (check if any object is on the tray (not sync with the sensors, only based on the knowledge db and task execution progress))

3. some files restructured.

4. config file can be loaded based on map-name accordingly ( environment variable ROBOT_ENV )
