The change-queue tester jobs can have some additional information that may be useful for understanding issues but is not reported anywhere ATM.

This information includes:

1. If the test failed because a build job failed, and which build job made it fail.

2. If the test failed during OST run, which suits failed.

This information should, at least, be presented in the test results screen, but may also be preserved and included in the email or Gerrit notifications about failing changes.
