ogcp: add support to view script output

Add view at /action/script/output to visualize the result of
/shell/run for multiple clients.

Use shell/output to request the execution data of the selected clients.

Each client element has execution timestamip (UTC), client ip, cmd,
return code and stdout of the executed command.
