This adds register-service command which can be used to add GATT services
to the application:
[bluetooth]# register-service 00001820-0000-1000-8000-00805f9b34fb
[NEW] Primary Service

Note: register-application still has to be called at the end to register
with bluetoothd as everything is done with ObjectManager.
