Add integration_test_just_read_one_downstairs, which creates three read-only downstairs, stops two of them, and confirms that a read-only upstairs can still activate and read from the remaining single downstairs. Also add a stop() helper to TestDownstairs so a test can bring an individual downstairs down while keeping the rest of the set running.
Augment integration_test_just_read_one_downstairs to manually send a flush after the first read, then confirm a second read completes successfully. With only one downstairs running, the flush still acks because the two stopped downstairs have their jobs moved to Skipped, so the flush is complete on all clients rather than hanging.

There was a problem hiding this comment.
Flushes won't be sent to read-only parents, you'll have to change the structure of the VCR to put this under sub volumes instead

Added a test to verify that a read only volume that can connect to just one downstairs will be able to activate and read from that volume.
Shade was being thrown on Crucible, and this test was written in part to confirm that a single downstairs is all you need to talk to a RO volume.

These slights were handled, and Crucible's good standing was returned.
