Change Horizon RDS farm machine count

Changes the amount of RDS hosts in a Horizon Farm.

This action should be executed against a Horizon endpoint machine (one which has the HZ Primary Connection Server column populated in ControlUp Console). The script uses the target machine to determine the connection server address, and is executed on the machine running ControlUp Console.

This script requires VMWare PowerCLI to be installed on the machine running the script.
PowerCLI can be installed through PowerShell (PowerShell version 5 or higher required) by running the command ‘Install-Module VMWare.PowerCLI -Force -AllowCLobber -Scope AllUsers’
