TINKERPOP-1761: Cancel script evaluation timeout
https://issues.apache.org/jira/browse/TINKERPOP-1761
I basically added the code again which was wrongly removed in
TINKERPOP-1714, plus added a test. All unit tests passed and I confirmed
manually that this fixes the issue I experienced.

TINKERPOP-1761: Cancel script evaluation timeout in when script evaluation
finished.
----
> GremlinExecutor: Timeout future not cancelled on successful script evaluation
> -----------------------------------------------------------------------------
>
> Key: TINKERPOP-1761
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1761
> Project: TinkerPop
> Issue Type: Bug
> Components: groovy
> Affects Versions: 3.2.6
> Reporter: Konstantin Müller
>
> This bug seems to be introduced by TINKERPOP-1714. The timeout future in
> GremlinExecutor.eval() is not cancelled when the evaluation future is
> completed successfully before the timeout (lines 304ff). This was done
> correctly before the changes introduced by TINKERPOP-1714. Code to reproduce:
> {code:java}
> try (GremlinExecutor executor =
> GremlinExecutor.build().scriptEvaluationTimeout(15_000).create()) {
> executor.eval("1+1").get();
> } catch (Exception e) {
> // NOOP
> }
> {code}
> When the code leaves the try-block it calls GremlinExecutor.close() which
> will clean up executorService and scheduledExecutorService, but because the
> timeout future is not cancelled this will hang until the future is finished
> (here 15s).
> Workaround: Provide an own ExecutorService when constructing a
> GremlinExecutor instance and cancel all tasks when the script evaluation is
> finished successfully.
