This issue is to add a feature to escalator to ignore nodes with a custom (Condition or annotation) from scale down events. The effect would be nodes can remain uncondoned and attached, but escalator won't delete it. These could also be exempt from tainting.
Something like Condition: EscalatorIgnore
Similar to a soft maintenance mode, where cordon isn't appropriate because the node still should get workloads.
