Make busybox image configurable

[ponchofiesta]

SUMMARY

Actually major docker images are configurable via .env file. But the busybox image is hard coded into compose file. When using private docker registries it is necessary to change all image names to a local registry.

OS / ENVIRONMENT / Used docker-compose files

• docker-compose_v3_alpine_mysql_latest.yaml
• compose_databases.yaml

  db-data-mysql:
  image: busybox
