    .DESCRIPTION
        This script will automaticly download the certificate from your vCenter server and import it. Then get the thumbprint and create a Citrix hosting connection.
        Run the script on your Delivery controller or change line 35 to your delivery controller URL.
    .EXAMPLE
    New-vCenterHostConnection -vCenterURL "https://vcenter.domain.com" -vCenterUsername "DOMAIN\Administrator" -vCenterPassword 'Password01'

    This will create a new vCenter hosting connection to https://vcenter.domain.com with the user DOMAIN Administrator.
