vSphere Cloud Provider fails to attach volume due to "Permission to perform this operation was denied" error.

Issue

• AttachVolume.Attach failed for volume "pvc-*": ServerFaultCode: Permission to perform this operation was denied error when OpenShift attempts to add vmdk to virtual machine hosting OpenShift node.
• Persistent Volume cannot be mounted to Pod when using vSphere Cloud Provider due to permission issues in VMware vSphere.
• VMDKs are created in the folder kubevols in VMware datastore but the vmdk is not attached to the Virtual Machine.
• Pods are stuck at Creating but PVC shows as bound to PV when using vSphere Cloud Provider.
