fcli ssc appversion: Add status information

[rsenden]

It would be good to have a column in fcli ssc appversion * table output informing the user of the current status of each application version, like whether metrics refresh is required, whether an uploaded artifact requires approval, empty (no artifacts uploaded/processed yet), ...
