Builds the operations adding desired number of AdGroups to given Campaigns.

  Note: When the AdGroups are created, they will have a different Id than those
  generated here as a temporary Id. This is just used to identify them in the
  BatchJobService.

  Args:
    batch_job_helper: a BatchJobHelper instance.
    campaign_operations: a list containing the operations that will add
      Campaigns.
    number_of_adgroups: an int defining the number of AdGroups to be created per
      Campaign.

  Returns:
    a list containing the operations that will add the desired number of
    AdGroups to each of the provided Campaigns.
