[NO ISSUE][OTH] Introduce DatasetFullyQualifiedName
- user model changes: no
- storage format changes: no
- interface changes: no
Details:
- Introduce DatasetFullyQualifiedName that is used to represent
a dataset's DataverseName as well as its name.
- This new class can be used as an identifier for a dataset rather
than using a Pair object of a DataverseName and a String.
