[Core] Allow configuring default autostop time for controllers

[romilbhardwaj]

User wanted to let job controller run for longer to speed up log fetching and future job submission. We don't seem to have any documented way to control the autostop duration. Maybe add to config.yaml?

skypilot/sky/core.py

Lines 291 to 296 in a80208f

	if idle_minutes_to_autostop is not None:
	raise ValueError(
	'Passing a custom autostop setting is currently not '
	'supported when starting SkyPilot controllers. To '
	'fix: omit the `idle_minutes_to_autostop` argument to use the '
	f'default autostop settings (got: {idle_minutes_to_autostop}).')

@romilbhardwaj if no one's working on this can I try to tackle this?

[romilbhardwaj]

Hey @kyuds - thanks for your interest. We discussed this and the team needs to finalize the design for this before we work on this.

I'd recommend taking a look at other good first issues, perhaps #4769?

Added for controllers in #5230, and now being generally supported in task.resources: #5577
