Review comment:
This is something that needs to be fixed form the Twister2 side first,
currently the submit method returns once the job is complete, and if it returns
with the state as "RUNNING" it means that the job terminated and did not
complete. This can be fixed once the issue is fixed on the Twister2 side. I
hope keeping it as is for now is OK for now.
