[FLINK-5718] [core] TaskManagers exit the JVM on fatal exceptions.
*This adds a feature requested by a user for production stability.*
Certain exceptions should not be attempted to be handled by the
TaskManager, because they indicate that the JVM is corrupt. When the task
throws such an exception, the TaskManager simply forcefully and immediately
exits the JVM.
Optionally, the `OutOfMemoryError` can also be set to cause such immediate
JVM termination, via the `taskmanager.jvm-exit-on-oom` config option.
### Tests
This adds a test that tests the option and the actual process kill (via a
spawned test process).
### Documentation
This adds the `taskmanager.jvm-exit-on-oom` to the `setup/config.md` docs.
