For deleted recurring_tasks

[tmimura39]

Hi, Let me ask you a question about #272.

This support is very convenient as it allows recurring_tasks to be checked in MissionControl.　thanks 👍

However, there seems to be a problem with “recurring_tasks deleted from the YAML configuration file” that continue to remain on the MissionControl dashboard.

This is because we only process create or update for SolidQueue::RecurringTask.

solid_queue/lib/solid_queue/dispatcher/recurring_schedule.rb

Lines 43 to 45 in 7901a8e

	def persist_tasks
	SolidQueue::RecurringTask.create_or_update_all configured_tasks
	end

We do not think this is a major issue since the task does not continue to run, just remains on the MissionControl dashboard.
However, as the recurring_task setting is repeatedly added and removed, the MissionControl dashboard becomes polluted.

Is this the intended behavior?

Yes, it's intended, for now. The reason is that the current setup allows you to have multiple dispatchers, running different recurring tasks so a single dispatcher can't delete all tasks that aren't in its configuration because they might belong to a different dispatcher with a different configuration.

I plan to improve this, though, and clean up these old tasks. I have other improvements that I need to implement for recurring tasks, so I'll do all those together.

Thanks for the reply!

Yes, I agree. I didn't think it would be easy.

I'm looking forward to seeing more improvements in the future!
