take and change a copy of the current run so we'll change newRun and use curRun
status for logic decision. In this way result are reproducible or they will be
affected by the random run.Tasks map iteration order.
Handle the task dependencies conditions:
* on_success (default if no conditions are specified)
* on_failure
* on_skipped
Not the runservice won't stop run but continue executing tasks that depends on a
parent also if this is failed
