Configurable saving interval for WOPI revisions

1 Initial Problem

Revisions of files that have been edited with WOPI automatically create drafts as soon as editing is exited. However, if the content has been deleted in the meantime, the content edited up to that point will also be deleted. The results of editing can then no longer be restored via the drafts of the file.

2 Conceptual Summary

The administration should therefore be able to define an automatic storage interval. This function can be activated by the administrators. This function shall be deactivated by default in order to minimize storage usage. The administrator would have the opportunity to decide, wether the current behaviour (save when leaving Edit-Mode) or an automatic, timebased saving should be used. It should also be possible to configure the interval for automatic saving.

This option shall effect the behaviour of all fileobejects that use the WOPI-API for editing.
