Lada,

there is no point in changing the definition of {+restconf}/data since
this would lead to interoperability issues and hence {+restconf}/data
remains what it is.

Yes, the new datastore names are longer but we did not want to require
globally unique datastore names (which would require some form of a
registry and that everybody uses the registry).
