  <issue>
  [GCP] Runners are not started.
  I pulled master and tried to evaluate libfuzzer against honggfuzz in 5 trials for 1 hour on 1 benchmark (mbedtls_fuzz_dtlsclient). It doesn't generate the report anymore. The web bucket is empty, the experiments-result folder does not exist in the data bucket, the SQL database is empty, and the Error Reporting gives the following error:
  ```
  ValueError: Empty experiment data. Message: Error generating HTML report.
  at validate_data (/work/src/analysis/data_utils.py:21)
  at generate_report (/work/src/analysis/generate_report.py:132)
  at output_report (/work/src/experiment/reporter.py:43)
  ```
  
  I deleted authorization keys of the service account. I deleted the old and set up a new SQL database (incl. `alembic upgrade head`). I cleaned out the container registry (by deleting the `container` folder in the corresponding bucket). I cleaned out the Cloud Builds (by deleting `source` folder in the corresponding bucket). It recreates the containers and builds, when I start the dispatcher. The dispatcher runs properly. I SSH'ed into a random runner: `docker images` and `docker ps -a` return empty-handed. Is the recent setup gcr.io/fuzzbench-specific? Any suggestion to debug?
