Miscelanous fixes after the release of the artifacts

1) Made sure that the target directory from where the controller runs
doesn't include the version else after every release we need to change
the launchers and all the jenkins jobs
2) Change config.ini to pick the new snapshot
3) Change the launchers to use the new target directory containing the
controller
4) Avoid to build the third-party given they are mostly unchanged
since a while, that will save build time.
