`_flush` should block by default (#20597)
This commit changes the default behavior of `_flush` to block if other flushes are ongoing. This also removes the use of `FlushNotAllowedException` and instead simply return immediately by skipping the flush. Users should be aware if they set this option that the flush might or might not flush everything to disk ie. no transactional behavior of some sort. Closes #20569
