Add a Job to a batch by position

[AbdelkaderBah]

There is a use case where you may want to add a Job to within position or index on a BATCH.

For example, let's say you have a BATCH of API calls, then API token expired you may need to refresh it through a new JOB (API call), it should prepend (precedent to) the next jobs

$this->batch()->prepend([
  new RefreshTheAPI,
  $this # maybe retry current task too directly after the Refresh...
])

NOTE: It may be handy to reconstruct the BATCH in order to fully customize it at any given time.
