Add DCOSWindowsAgentSetup.ps1 used in the CI

This is just a wrapper over the main init script from
http://dcos-win.westus.cloudapp.azure.com/dcos-windows/stable/

It does a couple of additional steps required in the CI:

* Enable WinRM on the DC/OS Windows agents. This is going to be
  used to execute remote calls from Linux
* Enable SMB firewall rule to allow logs collection through
  the default SMB share
* Enable Docker debug logging
