Feature Request: tail job and deploy logs with return code

[reconbot]

I'd like to be able to create a job and tail it's output having the cli exit 0 if the job is successful or something else if the job fails. eg.

render jobs create srv-XXXX --confirm -o text --start-command 'start_task' --wait --tail

From what I can tell the api might not give us the return code of the command but it does tell us if it failed or not. This would allow my team to dispatch tasks from a CI system (along with all the CI system's security and auditing controls) and report output and receive notice of errors to the jobs there.

Prior art would be heroku run -x. This would also be quite helpful for deploys.

Thanks this CLI is a major step up!
