suppress verbose MongoDB INFO logs in docker

- Add all logging components with verbosity 0 in mongod.conf
- Add WiredTiger verbose=[] to suppress checkpoint messages
- Add --quiet flag to mongod command
- Change healthcheck from mongosh to TCP port check to avoid
  connection metadata spam every 30s
- Increase healthcheck interval from 30s to 60s
