HDX Connectivity Health

<#  
.SYNOPSIS
        The script makes an HDX connection to a specific XenApp server (6.0 and above) in order to check the server's health.
.DESCRIPTION
        The script runs on the ControlUp Console computer and initiates an HDX connection against one or more
        XenApp servers in order to check the server's health. The script does not perform any actual login activity
        to the targeted XenApp server. After the connection is initiated the login connection will disappear after 40 
        seconds.
.PARAMETER ServerName
        This script gets only one parameter which is the server name. The server name is the $arg[0] parameter and is mandatory.
.EXAMPLE
        XenAppHDXConnectivty.ps1 XenAppServer005
.OUTPUTS
        Text describing the connection launch status
