      Cause: The master node tolerations were added so that the node plugin pods could be scheduled on HCP nodes.
      Consequence: But with convergence now CSI is deployed by client operator always. This means node plugin pods are getting schedules on master nodes even in normal odf clusters.
      Fix: We are removing default master node tolerations for the node plugin pods. We will implement another way to specify any kind of tolerations for the node plugin pods.
      Result: csi Node Plugin pods no longer schedule on master nodes
