First customization to avm99963-bugs

- Only a service is used (default) in order to keep usage within Google
  Cloud's free tier.
- Settings have been adapted.
- Only a single DB instance is used (primary).
- Some cron jobs are executed less often.
- |threadsafe| has been set to "yes" so the single instance can serve
  concurrent requests (otherwise the search/list issues function
  breaks).
