Cancel job and collect logs improvement

[joergboe]

When I cancel a job there should be a possibility to cancel and download the job logs in one step. This should be implemented like the streamtool command canceljob with option --collectlogs. Because this is the only way to get the logs when the job is shutdown.

This is currently not supported by the Streams REST API and will require changes from the Streams team to add this functionality. We'll look at adding this.
