[FLINK-3853] [gelly] Reduce object creation in Gelly utility mappers
Gelly contains a set of MapFunction between Vertex and Tuple2 and between
Edge and Tuple3. A Vertex is a Tuple2 and an Edge is a Tuple3, and conversion
in the opposite direction can be performed with a single object per MapFunction.
This only applies to the Gelly Java API. Scala tuples are not related to
Vertex or Edge.
