feat: Set ansible_connection to winrm for Windows hosts

This changes the inventory plugin so that it sets the ansible_connection
to winrm if it detected a Windows host. If it did not detect a Windows
host the ansible_connection is no longer set, so Ansible falls back to
its default value of ssh. The detection of SSH services for hosts using
winrm is disabled.
