Async commands

We need a way to dispatch background jobs to a queue. We could make a CLI-only interface for starters. We already have a scheduler component which might come in handy, though still tbd.

This is actually the one thing keeping me away from trying it out.

Gotcha! Thanks for that feedback, we might reprioritise stuff in the coming days :)

I made a rough sketch of what the system should look like:

Just thinking here, but I think something like Horizon should be built-in. Not talking about the interface (which I don't think is even necessary), but the functionality, with customizable environments and balancing strategies.

It's personally super rare that I don't need that and that I only use the built-in queue, so I think Tempest should also have that built-in.

Hands down agree, @innocenzi. Long term, I'd really love to see Tempest play nicely with microservices/other languages in the queue as well. This is something that I firmly believe PHP to be lacking a good implementation of.

By way of update here, @brendt and I had this conversation a little bit and the starting point (for v1) may simply be async commands executed by a console runner that can then be rebuilt (under the hood) on top of a proper queue system post v1.

This is all pending Brent's post-weekend thoughts. 🙃

My mid-weekend thoughts are: for v1, we're going to add async support in the commandbus. There won't be any balancing strategies, but you will be able to push tasks to the background. I also don't think a UI is necessary, but there will be a CLI-based monitor.

After v1, we can expand on it as Aidan is describing
