Template command allow displaying a template from a relative or absolute path

This would depend on #1477 being implemented

If the new command can use templates from an exernal path, it would make sense that the template command could list information about those templates as well.

Start by reviewing ChocolateyTemplateCommand.cs at the linked location and issue #1477, since this work depends on external-template support being implemented there. Done means the template command can display information about templates addressed by both relative and absolute paths.
