> Be able to accelerate time in SLS.To do that, a {{timescalefactor}} parameter is introduced (default value = 1)
> With if we use a time factor of X, time in simulation will be X times faster than real. Time in generated CSV will be modified a well to have the same result as if we don't use {{timescalefactor}}.
> For example, it permits to run a simulation of one week of jobs in just one day if we use {{timescalefactor=7}}
> To do that a ScaleClock object has been introduced, which implements {{org.apache.hadoop.yarn.util.Clock}}. It also extends {{com.codahale.metrics.Clock}} for metrics reported in csv.
> All objects used for the simulation now use a shared reference to a {{org.apache.hadoop.yarn.util.Clock}} instance to get current time instead of using {{System.currentTimeMillis()}}
> A new optionnal parameter {{--timescalefactor=<factor>}} has been introduced on {{slsrun.sh}} script.
