> Option to expire SDK worker environments

> We discovered that Python SDK workers are susceptible to memory leaks that
> are quite hard to identify and/or fix. This becomes an issue in streaming
> pipelines, where the workers run "forever". It would be good if the user has
> an option to recycle the workers when there is no other practical way to
> address (slow) resource leaks.
