[BUG] [SPRING-CLOUD] Remove dependency management tag

Created by: MelleD

In the generated pom of spring cloud a dependency management tag is inserted by the template, although the parent pom is overwritten. Normally the parent pom already defines dependency management. For this reason, version conflicts can occur

Possible solutions are:

1. Introduce new boolean flag in the config
2. Dependendcy management is not inserted as soon as the parent pom is overwritten.

Are there any other solutions?
