[FLINK-6382] [gelly] Support additional types for generated graphs in…

… Gelly examples The Gelly examples current support IntValue, LongValue, and StringValue for RMatGraph. Allow transformations and tests for all generated graphs for ByteValue, Byte, ShortValue, Short, CharValue, Character, Integer, Long, and String. This closes #3779
