Mark volume as detached when node does not exist for vsphere
If node does not exist, node's volumes will be detached
automatically and become available. So mark them detached and
return false without error.

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"
If node does not exist, node's volumes will be detached
automatically and become available. So mark them detached and
return false without error.
