Review comment:
While protecting against double closes is generally a good idea, I don't
think we should attempt to do that here.
First, we do not have insight into exactly what operations a given `Closer`
is performing. It _may_ be reasonable for two separate `Closer`s to be created
for the same underlying resource and to have separate `CloseableResources`
representing the different aspects that require cleanup (e.g., if those have
different lifecycles).
Second, as Eugene pointed out, `AutoCloseables` should _usually_ be
idempotent, so guarding from double-closes here is overstepping our bounds.

> There needs to be a way to execute Java-SDK pipelines against a portable job
> server. The job server itself is expected to be started up out-of-band. The
> "PortableRunner" should take an option indicating the Job API endpoint and
> defer other runner configurations to the backend itself.
