Title: Stager fixes

* switch non-crucial logging information in verbose mode, to avoid polluting the logs
* Job killing signal should also affect the stager (https://github.com/DIRACGrid/DIRAC/issues/1510)
Make sure to only cancel file staging for files with no relations with other tasks (jobs) but the killed ones. "Canceling" is removing all information on these tasks, from the SMS DB.
