OutputParser: Allow to flush pending tasks.

Add a way to flush out tasks from the outputparsers. This is necessary
to make parsers that keep state more robust.

Flush parsers (once) before adding any new task. This keeps the sequence
intact.

Flush all parsers once the parsing is done to make sure there is no task
queued somewhere.
