Simon Willnauer bd51d7a07f Add wait_if_ongoing option to _flush requests
This commit adds the ability to force blocking on the flush operaition
to make sure all files have been written and synced to disk. Without
this option a flush might be executing at the same time causing the
current flush to fail and return before all files being synced.

Closes #6996
