DSC Pull Scenario 1 (Pull Configuration).ps1

<#
This scenario demos a DSC pull server. The lab must have an internet connection in order to download additional required bits. PowerShell 5.0
or greater is required on all DSC pull servers or clients. Please take a look at introduction script '10 ISO Offline Patching.ps1' if you
want to create a Windows Server 2012 base image with PowerShell 5.

First a domain controller is setup. Then AutomatedLab (AL) configures the routing, a web server and the CA. This scenario demos
a DSC pull server that is encrypting the network communication using SSL. For this AL creates a new certificate template
(DSC Pull Server SSL. The DSC pull server requests a certificate using this template and configures DSC accordingly.

AL also creates a default DSC configuration that creates a test file on each DSC client. The name of the file is TestFile_<PullServer>.
The pull server the configuration is coming from is part of the file name as a client can have multiple pull servers (partial configuraion).
