  The Maps team gave us a build of their test. The static files are stored in

  Note: the file maps_perf_test/load_dataset is a large binary file (~3Mb),
  hence we upload it to cloud storage & only check in the SHA1 hash.

  The command to upload it to cloud_storage is:
  <path to depot_tools>/upload_to_google_storage.py \
