Summary: TinkerGraphComputer does not shutdown ComputerService

Project: TinkerPop
Issue Type: Bug
Components: tinkergraph
Affects Versions: 3.2.3
Reporter: Ted Wilmes

I haven't seen any issues in normal usage, but while benchmarking
`TinkerGraphComputer` with JMH, I noticed the forked JVM was hanging and had to
be forcibly killed by JMH.

<JMH had finished, but forked VM did not exit, are there stray running threads?
Waiting 19 seconds more...>
{code}
The {{TinkerWorkerPool}} is being closed but not the {{ComputerService}} which
causes the hang.
