Skip Deployment of integration-test and samples artifacts

General Description

As voted on the mailing list (vote still running as of writing this issue), the deployment of the integration tests artifacts and samples artifacts to maven central can be skipped.

Technical change

Add the property <maven.deploy.skip>true</maven.deploy.skip> to artifacts which are part of the integration tests and/or samples modules.

Rationale

Those artifacts are usually only interesting for development (ITs) and for reference used by other developers (samples).
Binary artifacts should not be needed for those, especially not on maven central.
