Using hash/fnv to generate the vmName

Browse Source 
vSphere has limitation of 80 characters for vmName.
        with vsphere-k8s prefix and "vmdisk.volumeOptions.Name" vmName can become easily bigger than 80 chars.
        Used hash funciton just of the "vmdisk.volumeOptions.Name" part as cleanup dummyVm logic depends on prefix "vsphere-k8s"
