This admin utility can be used on upgrade after the customer
added ha_datastore_id to the nsx.ini configuration, in order
to update the deployment of existing edges.

including the datastrore_id, ha_datastore_id, edge_ha
The edge current resource pool & appliance size will not change
Usage example:
nsxadmin -r edges -o nsx-update --property edge-id=<edge-id>
--property appliances=True
