Thomas Draebing 91d62c0776 Use the environment variables provided by the GerritCodeReview-plugin
So far the pipeline described in the Jenkinsfile queried Gerrit to get
the change metadata. By now the GerritCodeReview provides this data as
environment variables. This reduces the boilerplate code needed in the
Jenkinsfile.
