Add an info button in a new column of the 'Save code now' requests list.
By clicking on it, a popover will be displayed while a fetch request will
be sent to the backend to get the loading task execution info (if available)
associated to the 'Save code now' request.
Once the response of the fetch request is received, task execution info data
will be formatted and displayed in a table.
