This will help removing Flakiness Surface backend code from ChromiumDash and move all interaction with BQ to test-resuls.appspot.com, so we can remove chromiumdash service account from the list of users able to access the data.

By moving the logic, we will migrate all code to Go and remove many libraries that were added to ChromiumDash repo to simplify writing tests. This in turn will simplify migrating the repo to infra repo and doing PRR. Another side-effect is that queries to the Dremel can be run in parallel using go-threads, which is much harder to achieve in Python.
