The following tests should be made less flaky by this change:
- TestFailedDataRepair
- TestOfflineNodeDataRepair
- TestUnknownErrorDataRepair
- TestMissingPieceDataRepair_Succeed
- TestMissingPieceDataRepair
- TestCorruptDataRepair_Succeed
- TestCorruptDataRepair_Failed
This follows on to a change in commit 6bb64796. Nearly all tests in the
repair suite used to rely on events happening in a certain order. After
some of our performance work, those things no longer happen in that
expected order every time. This caused much flakiness.
The fix in 6bb64796 was sufficient for the tests operating directly on
an `*ECRepairer` instance, but not for the tests that make use of the
repairer by way of the repair queue and the repair worker. These tests
needed a different way to indicate the number of expected failures. This
change provides that different way.
