[ARROW-2610] [Java/Python] Add support for dictionary type to pyarrow.Field.from_jvm

Description

The DictionaryType is a bit more complex as it also references the dictionary values itself. This also needs to be integrated into pyarrow.Field.from_jvm but the work to make DictionaryType working maybe also depends on that pyarrow.Array.from_jvm first supports non-primitive arrays.
