[Pharo-project] Cleaning up old Jenkins

Hi, We are preparing to move the new Jenkins infrastructure at https://ci.inria.fr This means that the old https://ci.lille.inria.fr/pharo/ Will be closed at some point the next months. THEREFORE: -> clean up old and dead projects. A project that fails since month can be deleted. -> unneeded projects can be removed. For Projects that you want to continue, please contact us so we can coordinate moving it to the new infrastructure. Marcus
