25 * Router job that takes jobs and enqueues them to their proper queues
27 * This can be used for getting sets of multiple jobs or sets of jobs intended for multiple
28 * queues to be inserted more robustly. This is a single job that, upon running, enqueues the
29 * wrapped jobs. If some of those fail to enqueue then the EnqueueJob will be retried. Due to
30 * the possibility of duplicate enqueues, the wrapped jobs should be idempotent.
