Ticket 49471 - Rename dscreate options
    
    Description:  Changed the names of the two positional arguemnts from
                  "fromfile" --> "install", and "example" --> "create-template"
    
                  Added option for specifying template file instead
                  of dumping the template to STDOUT
    
                  Finally added autocomplete arg parsing to the cli tools,
                  and used a unique file name in UI when creating template.
