Don't use Gradle build and configuration cache for releases (#662)

* Don't use Gradle build and configuration cache for releases

- don't enable Gradle build and configuration cache for the project, but recommend it for the developer
- explicitly enable Gradle build and configuration cache for CI test jobs
- let AboutLibraries generate lib definitions itself again
- also don't archive test results (sometimes fails and we never use the results)

* Add encryption key for gradle cache

* Only warn on configuration cache problems (caused by AboutLibraries)
