Add cvmfs default support for geant4.cern.ch
Decrease the number of resource updates.

This commit forces resource updates on task reception, start of task
execution, and final task report. This allows to send 'unforced'
resource updates less frequently (here every two minutes, rather than
every five seconds). The idea is not to send resource updates if nothing
interesting has happened at the worker.
