Is there built-in worker management or load balancing support?

[NiDHanWang]

When running multiple workers in production, I expect to have:

1. Worker Process Management: Automatically spawn, monitor, and restart worker processes that crash or become unresponsive
2. Load-Aware Task Distribution: Distribute incoming tasks based on worker load/capacity

After reviewing the arq codebase, I did not find build-in support for those.
Did I miss something in the documentation or codebase? Or is this intentionally left to external implementation.
