> Right now it's possible for a worker to connect to a worker of a different
> topology during a reassignment. Generally this happens very rarely in
> practice, and when it does causes ClassNotFoundExceptions.
> Add in a handshake when worker connection is first established, and ensure
> they agree on topology id. If they don't agree they shouldn't transfer any
> data, but neither should halt their process.
