WinRM Connection reset buy peer errors in AS2_Automation_Windows_FN02_Scripted_Install

Intermittent WinRM Connection reset buy peer errors in AS2_Automation_Windows_FN02_Scripted_Install:

```
[ERROR] ConnectionError: ('Connection aborted.', ConnectionResetError(104, 'Connection reset by peer'))

These don't seem to be related to the lambda timeout or lambda RAM allocation.

Start in lambda_function.py at lambda_handler line 181 and install_application line 50, then trace the WinRM call through the vendored winrm package paths shown in the traceback. Reproduce or instrument the intermittent failure and identify a reliable resolution; done means the connection-reset errors are explained and the installation flow handles them successfully.
