Feature #25170
Add Resilver Priority to Storage tab
Description
We need a resilver "scheduler". What that means, is we have sysctl's which will bump the priority of resilver IO. Users should be able to throw that into a schedule, such as off-peak hours, weekends, etc, where they can set resilver to be more or less aggressive in its IO usage. Where this lives in the UI is open for discussion, but having the feature will become far more important as disks get larger.

Updated by Ash Gokhale defaults are thus:
vfs.zfs.resilver_min_time_ms: 3000
vfs.zfs.resilver_delay: 2
vfs.zfs.scan_idle: 50
aggressive setting:
vfs.zfs.resilver_min_time_ms: 9000
vfs.zfs.resilver_delay: 0
vfs.zfs.scan_idle: 0
A larger scan_idle will prioritize the user workload.

Updated by Alexander Motin Ash, shall we do alike for scrub?
Ash told:
There are several shared timers and start vectors for 'idle' homework. Scrub may actually be prioritied by scan_idle. I'm afraid of introducing too many dials; they will be misued.

I think UI should provide just a single slider, while inside it may translate into any set of tunables.
