Improve docker compose development configuration for mysql monolith

[fkromer]

The hawkbit service depends on mysql healthy-ness only. The configuration could be improved by making it depend on rabbitmq as well. Potentially relates to "rabbit" related Spring Boot application properties.

ATM the monolith hawkbit application disables the auto-configuration of rabbitmq in the application.properties. A better way of solving this would be to use profile-specific configuration files like already done for the mysql dependency and postgresql dependency.
