Upgrade the Jenkins release job

1. Update the job configuration to fit the new CI (done)
2. Add a build job to build executables on every commit on the master branch (done with nightly builds)
3. Do not launch the tests suit if the branch name starts with wip (done)
4. Lower the console output to WARNING and create a ndrive-(linux|mac|windows).log with TRACE level. To artifact
5. Create one coverage file per OS (a single HTML document?). To artifact
6. No need for full stacktrace, standard lib traces are not useful and it adds to much noise (done)
