Displayed in all .status.taskID* fields.

stop: &TypeStringBool
type: string
description: |
Allows to stop all ClickHouse clusters defined in a CHI.
Works as the following:
- When `stop` is `1` operator sets `Replicas: 0` in each StatefulSet. Thie leads to having all `Pods` and `Service` deleted. All PVCs are kept intact.
- When `stop` is `0` operator sets `Replicas: 1` and `Pod`s and `Service`s will created again and all retained PVCs will be attached to `Pod`s.
