Support minimum_time for pipelines that return too quickly

[spencer-cdw]

We have a pipeline that takes 1 hour to run.
Occasionally see the pipeline silently fails after a few seconds/minutes.

Unfortunately the failure doesn't raise an exception or an invalid exit code, so the pipeline continues on.

We would like to have a flag similar to the timeout_minutes, however rather than setting a ceiling for the maximum time the task should run, we want a minimum time that the task should have taken
