Check job status when it terminates

[LanderOtto]

This commit introduces a check of the job status inside the run method of the ExecuteStep class. It is helpful to terminate other running jobs of the same step, because if a job exits with an error status, the entire workflow run must fail. Such a failure does not depend on the manager, as the failure is handled inside the _run_job method itself.

Before this commit, the step was checking the job status only when all the jobs terminated their executions (either successfully or not). However, such a behavior results in a waste of time and computing resources.
