Safe mode to pause non-essential changes
I'd like to be able to put the cluster into a "Safe Mode" during an incident.
For example, I'm responding to an incident or I suspect something's fragile or breaking, and I don't want any scheduled activities to make it worse or distract me. I also don't want to have to know what changes are scheduled, I want to pause them all regardless.
This would pause any scheduled or non-critical changes, like upgrades, building indexes, probably resyncs, etc.
But it would keep running cluster-safety/health-supporting mechanisms like auto-heal, and probably backups.
And it would put up a banner on the cluster so everyone else interacting with it knows that it's in safe mode.
