switch powershell script execution from daemon.rb to daemon.bat

running powershell script in daemon.rb could not be succeed, so I have to make a compromise to run it daemon.
This .ps1 is used to update ComputeName and workgroup, after these work
doen it delete itself and reboot computer.
In addition, we will move c:\razor_puppet.conf to puppet.conf in
daemon.rb. That mean we will treat c:\razor_puppet.conf as puppet agent
configuration if the c:\razor_puppet.conf exists.
