[CLASS DEVICE]: add attribute_group creation
Extend the support of attribute groups in class_device's to allow groups to be created as part of the registration process. This allows network device's to avoid race between registration and creating groups. Note that unlike attributes that are a property of the class object, the groups are a property of the class_device object. This is done because there are different types of network devices (wireless for example).
