Short form template (-T) option in cs server create doesn't work

The option is already set by a dependency, in the knife-windows gem: https://github.com/chef/knife-windows/blob/master/lib/chef/knife/winrm_base.rb#L75-L79, so the instructions in the README don't work.

I think the short form option should be removed, and the README updated. Should I create a PR for that? Thanks in advance
