DEPLOYITPB-4159 First attempt to send stdin over WinRM.

DOES NOT WORK with Python Daemon yet. Messages over stdin are sent, and in the Windows event log I an see that they're picked up, but there is no evidence that they reach the Python Daemon.
FIXME: a new Thread is created to pipe stdin form the OverthereProcess to WInRM. It seems that this Thread does not end properly, so you may have a very nasty resource / thread leak on your hands.
