Review comment:
Keeping each harness manager scoped to a job is an interesting idea. On the
other hand, doing so does require us to use another layer to actually cache and
manage the managers so that we don't have more than one per job per JVM. The
entire point of the harness manager is precisely to scope and reuse
environments for different operators running on the same machine (for the same
job).
It seems like the worker id should be part of the `EnvironmentSession` or
whatever we want to call it now. That also changes the flow of information to
and from the docker factory a bit (whoever creates/manages sessions is now
responsible for worker id generation), but that should be a simple refactor.
