Issue 50640 - Database links: get_monitor() takes 1 positional argument but 2 were given
    
    Bug Description:
    Cannot call dsconf ... chaining monitor due to invalid call to get_monitor.
    
    FTR: The other issue reported within, for the ... link-delete has already been
    fixed in commit c403a39.
    
    Fix Description:
    Use _get_link to get the named link, the same way some other functions in the
    file do.
    
    Also, merge and move _format_status to cli_base.
