It often takes a long time to fix a flake; meanwhile it takes a lot of time for sheriffs to identify whether to register a new flake for a failure. This CL adds automatic identifies identification of one know flake type. Once identified, it rewrites the error so that: 1. Flakes clustering tool that has only rudimentary clustering, places all flakes of this kind in the same cluster (not multiple ones like now). This is a step towards using clustering tool for monitoring flakes; 2. Sheriff immediately sees that the issue is known. Change-Id: I86a0762665cb21434289e1be00b60bd76fec4142
