      - Considering the possible number of new instance manager pods in a further system upgrade, this integer value ranges from 0 to 40.
      - One more set of instance manager pods may need to be deployed when the Longhorn system is upgraded. If current available CPUs of the nodes are not enough for the new instance manager pods, you need to detach the volumes using the oldest instance manager pods so that Longhorn can clean up the old pods automatically and release the CPU resources. And the new pods with the latest instance manager image will be launched then.
      - This global setting will be ignored for a node if the field \"InstanceManagerCPURequest\" on the node is set.
      - After this setting is changed, all instance manager pods using this global setting on all the nodes will be automatically restarted. In other words, DO NOT CHANGE THIS SETTING WITH ATTACHED VOLUMES."
