Allow to skip notification (and permanent storage) of reports for api endpoint

[dlangenk]

When requesting a report via the API, e.g. for machine learning purposes this generates a notification when the report is ready. If the report is simply used downstream for automated processing there is no need for a notification in Biigle / or via mail.

In addition reports are stored permanently by default. It would be great to allow add a flag to automatically delete them after a reasonable amount of time (say 4 hours or 1 day for API requests)

Adding a flag to the api endpoint to skip notification and a second one for non permanent reports would be great.

If the report is used for automatic processing, wouldn't it be more practical if the report is deleted with a subsequent API request, too? Then you can make sure the report is deleted exactly when you no longer need it instead at some random later time.

Adding a flag to "mute" the notification sounds good.

That sounds good.
