Their revision date should have been changed and the code + other YANG
imports adapted accordingly.

Note that:
- even if there is no ODL guidelines on the topic, this is IETF YANG
  recommendation.
- The RESTCONF payload will remain the same for end-users.
- JAVA API and Datastore contents may be affected
  (potential upgrade compatibility issue from existing Sodium instances)
