If you want to get rid of the VMs before a full cluster maintenance, you can simply "enable" retreat mode. 300 seconds. Retreat Mode allows the cluster to be completely shut down during maintenance operations. vCLS VM placement is taken care of by the vCenter Server, so user is not provided an option to select the target datastore where vCLS VM should be placed. This can generally happens after you have performed an upgrade on your vCenter server to 7. The solution for that is easy, just use Storage vMotion to migrate the vCLS VMs to the desired datastore. So it looks like you just have to place all the hosts in the cluster in maintenance mode (there is a module for this, vmware_maintenancemode) and the vCLS VMs will be powered off.
