Ensure -k is set to delegated hosts without a pass (ansible#71136)

* Ensure -k is set to delegated hosts without a pass

* Fix up some broken tests

* Update task_executor.py

one possible fix, the other is updating winrm to normalize on 'password' like the other connection plugins

* Add alias for winrm and fix incorrect assumption

* Make sure aliases are used for keyword options

* Conditionally run test if sshpass is present, fix sanity
