TINKERPOP-1921 Added hasNext() in gremlin-python
https://issues.apache.org/jira/browse/TINKERPOP-1921
Adds `hasNext()` to gremlin-python - pretty self explanatory. Would be nice
to get the rest of the GLVs done too. Also fixed some PEP8 formatting nags.
Builds with `mvn clean install -pl gremlin-python`

> Support hasNext terminal step in GLVs
> -------------------------------------

> Key: TINKERPOP-1921
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1921
> Project: TinkerPop
> Issue Type: Improvement
> Components: dotnet, javascript, python
> Affects Versions: 3.2.7
> Reporter: Florian Hockmann
> Priority: Major
>
> The GLVs don't have the {{hasNext}} terminal step which is very useful to
> check whether an element exists in the graph or not. Without this step, users
> have to write workarounds like {{limit(1).count().next()}} and check the
> returned count.
