Component: Queues/Workers

[StachuDotNet]

This Issue exists to collect many items that relate to "Queues/Workers" in Darklang. In Darklang-classic, queues only existed in our Cloud runtime (since that was the only runtime), but going forward we should have them supported for the Local/CLI runtime as well.

• [ ] uncomment the _events.dark test file. (This was quite flaky in CI, but we decided to put addressing that for a bit, and have uncommented this until we have some focus on queues/workers)
• [ ] in Tests.fs, uncomment the usage of Queue.Tests.fs
• [ ] bring back Queues, in some minimal capacity
  • why is the issue happening:
    • we clear the Queue DB
    • we add a message to check if the queue exists
    • multiple servers are doing that same thing
• [ ] add timelimit for queue execution
  • the goal here is to limit the execution of an item on the queue
  • To end computation that runs over (lets say) 3 minutes. I'm not sure it's possible without adding cancellation tokens everywhere - maybe that's what we'll need to do?
• [ ] Workers should be typed
• [ ] emit's arg should be real worker name/reference, not a string
• [ ] worker counts should work
• [ ] it should be clearer if a worker is paused
• [ ] workers should have dead-letter queues
• [ ] review Rollbar: "Deadline Exceeded" (#3815)
• [ ] disable workers which do nothing (see #3958)
