In #10063 we will switch BlobWriter to use the owned buffers IO buffered writer, which implements double-buffering by virtue of a background task that performs the flushing. That task's lifecylce must be contained within the Timeline lifecycle, so, it must hold the timeline gate open and respect Timeline::cancel. This PR does the noisy plumbing to reduce the #10063 diff.
