Changes in the oh_cp and oh_mv utilities

The content structure of the ROOT files which are created by those utilities when --use-offline and command line parameter is used has been changed to the same one as provided by the MDA service. In particular the Run and LumiBlock folders have been moved up in the hierarchy. So the old structure which was looking like:
    /is_server_name/histogram_provider_name/run_number/lb_number/histogram_name
has been changed to:
    /run_number/lb_number/is_server_name/histogram_provider_name/histogram_name
In addition to that when the run_number is requested to be added to the name of the file, created by those utilities, they are as well using the same format as MDA, e.g. :
r0000163478_Histogramming.root
