[v25r0] Forked dirac-wms-cpu-normalisation, see DIRAC PR #2904
For: ILCDIRAC-661 This reduces the memory footprint of the DIRAC CPU Normalisation function by using xrange instead of range. Needed to copy the getCPUNormalization function, so that we can change it.
If DIRAC works correctly having the dirac-wms-cpu-normalisation script in ILCDIRAC will override the one from DIRAC during dirac-deploy-scripts.
