Add a (increasing) delay when submitting multiple jobs in a batch

This is related to #1384. For most situations the implementation in #1384 is enough, but in some auto-confirmation situations we start multiple types of jobs. For example, after a demux we start both the hisat and legacy pipelines and we want all the hisat jobs to be scheduled before the legacy jobs.
