The bucket sizes that are being used for build and stage durations is too heavily slanted to very short durations (like RPC call durations).

Given that we have build and stage times that go up to 8+h, it'd be useful to maintain at least 10-15 minute granularity all the way up to 12h instead of having buckets that are longer than an hour at that size.

Here are the current buckets for the build durations:
  Query(Fetch(Raw('monarch.acquisitions.Task', '/chrome/infra/chromeos/cbuildbot/build/durations'), {'metric:build_config': RegexpMatch('master-release')})
        | Window(Delta('1d'))
        | GroupBy(['metric:build_config'], Sum()),
        '1h', '1h')
