[debian] Introduce a cubicweb-ctl3 binary package This packages conflicts with cubicweb-ctl binary which uses the python2 library. It is meant to ease upgrade of existing installation during the migration from python2 to python3: in particular, by installing cubicweb-ctl3, scripts calling "cubicweb-ctl" command should still work as before.
