[#81] Clarify that attribute names must be unique

Browse source 
All types of attribute keys must be unique and can't be repeated in the same
entity.

- Containers with duplicated attribute keys must not be accepted by InnerRing on
  creation.
- Nodes with duplicated attribute keys can't be accepted to NetMap by InnerRing
- Objects with duplicated attribute keys must be considered invalid and not
  accepted in PUT operations
