Title: Fix null shutdown timeout in ExecutorServices

`ScheduledExecutorServiceBuilder` defines no default `shutdownTime` or `shutdownUnit`. These are passed to `ExecutorServiceManager` which in turn uses them verbatim on `ExecutorService#awaitTermination(long, TimeUnit)`, potentially causing a `NullPointerException`.

Adding default values resolves this problem.
