object_identity_state attributes
......................................................................
nokia_site: Add object_identity, object_state and object_identity_state
attributes
Note: these are cosmetic changes so far, the plan is to use them
in the future to finetune the Nokia OML and RSL bootstrap logic.
Thanks Domi for helping with the code!
