Fix for Policy based volume provisioning failure due to long VM Name in vSphere cloud provider
Dummy VM is used for SPBM policy based provisioning feature of vSphere cloud provider.
Dummy VM name is generated based on kubernetes cluster name and pv name. It can easily go beyond
vSphere's limitation of 80 characters for vmName.
To solve the long VM name failure hash is used instead of vSphere-k8s-clusterName-PvName
