java-springcloud: No dependency management if parent overridden

[MelleD]

If a separate parent pom is specified, there should be no depdendency management

fixes #3230

PR checklist

• Read the contribution guidelines.
• Ran the shell script under ./bin/ to update Petstore sample so that CIs can verify the change. (For instance, only need to run ./bin/{LANG}-petstore.sh, ./bin/openapi3/{LANG}-petstore.sh if updating the {LANG} (e.g. php, ruby, python, etc) code generator or {LANG} client's mustache templates). Windows batch files can be found in .\bin\windows\. If contributing template-only or documentation-only changes which will change sample output, be sure to build the project first.
• Filed the PR against the correct branch: master. Default: master.
• Copied the technical committee to review the pull request if your PR is targeting a particular programming language. @bbdouglas (2017/07) @sreeshas (2017/08) @jfiala (2017/08) @lukoyanov (2017/09) @cbornet (2017/09) @jeff9finger (2018/01) @karismann (2019/03) @Zomzog (2019/04)

Description of the PR

If a separate parent pom is specified, there should be no depdendency management, because that can lead to version conflicts

Is there any objection to merge this?
If this is into the next release, it would make a lot easier for us.
Thank you

This might be because of concurrent merges
