[input/sites/**] Add as nodeset the cluster name

    To do that:
    gawk -i inplace -f awkfile input/grid5000/sites/**/*.yaml

    awkfile:
       /nodeset:/  { n = split(FILENAME, parts, "/"); print "    nodeset: " parts[n-1];}
       !/nodeset:/  {print $0}

Also set two different nodeset (since the cluster is divided in two teams)
