Fix Powerflex e2e alternate values tests in OCP cluster

[ashleyvjoy]

Description

In OCP clusters, the master nodes have the taint - key: "node-role.kubernetes.io/master" and not - key: "node-role.kubernetes.io/control-plane" so the controller pods are looking for a taint that doesn't exist in the E2E test scenarios that uses existing alternate values file. The toleration - key: "node-role.kubernetes.io/master" should be added. More details in the ticket

Merged main into this branch and addressed merge conflict, which should bring UT coverage up unless code was added and not tested in this branch.
