I'm not sure if this change will affect our queries for false rejections. 

But in my opinion, this kind of flaky tests can be classified as 'hidden flakes' that we plan to support in the near future.

It shouldn't change the false rejection queries, since those are based on the results of the build, not individual steps in the build.

Yes, cq false rejection queries doesn't need to change, but with the 'retry with patch' steps, a lot of flakes won't cause false rejections now, which means that they won't be detected now.

So, in order to surface those flaky tests failed in 'with patch' steps but succeeded later in 'retry with patch' steps, a new query is needed.

Yes, definitely other queries will need to change :).

[Findit] Add query to detect retry with try hidden flakes

This CL adds a query to detect flaky tests hidden by retry with patch
steps. The retry with patch can be either a success or failure:
1. t1 and t2 failed in with patch step, and both t1 and t2 passed in
   retry with patch step. The retry with patch step is a success and
   both t1 and t2 are valid flaky tests.
2. t1 and t2 failed in with patch step, and t1 passed in
   retry with patch step, but t2 failed again. The retry with patch
   step is a failure, and t1 is a valid flaky test, but t2 is not.

[Findit] Adapt the model for retry with patch flakes

This CL adapts the model for retry with patch, and it is a pure
refactoring CL, and once this CL lands, data needs to be migrated.
