$./ceph osd unset noout
unset noout <---------------------- no message if flag is not set it gives same message "unset flag-name" 

- Currently if we set or unset already set and unset osdmap flags we do not get any message like

- <flag_name> flag is already set - if flag is already set and we are setting it
- <flag_name> flag is not set - if flag is not set and we are unsetting it
