In general Docker Compose provides an
extendsanddepends_onfeature which could be use in combination. However, some newer versions of Docker Compose do not support to extend a service A with a service B which defines a depends_on.In order to support many Docker Compose versions (not only a working version such as v2.21.0) this Pull Request shifts the
depends_onfeature from service B to the top-level service A.
