Setup vSAN Stretched Cluster DRS Rules
This script can be run against a vSAN Stretched Cluster to create Host Groups and VM Groups.
The script requires PowerCLI 6.5.1, released 4/20/2017 and has been tested against vSAN 6.6.
Using PowerCLI 6.5.1, this could still be used against vSAN 6.1/6.2/6.5 Stretched Clusters.
VM's that do not have a Site Affinity vSAN 6.6. Policy, will require a VM Tag for proper site assignment.
Also, at least one VM must reside in a site for a VM Group to be created for that site.
