.SYNOPSIS
This script selects local datastore based on the following rules:
- Name starts with ds-local-Datastore
- Datastore FreespaceGB > 400 Gb
- VM count on the datastore < 2
.PARAMETER VIServer
vCenter address (Example "10.0.1.16")
.PARAMETER VIUserName
vCenter username (Example "Administrator")
.PARAMETER VIPassword
vCenter password (Example "12345678")
