    Performs the email sending task.

    Sends an email to a list of recipients.

    Inputs are:
      * `entry_id`: id of the InstructorTask object to which progress should be recorded.
      * `email_id`: id of the CourseEmail model that is to be emailed.
      * `to_list`: list of recipients.  Each is represented as a dict with the following keys:
        - 'profile__name': full name of User.
        - 'email': email address of User.
        - 'pk': primary key of User model.
      * `global_email_context`: dict containing values that are unique for this email but the same
        for all recipients of this email.  This dict is to be used to fill in slots in email
        template.  It does not include 'name' and 'email', which will be provided by the to_list.
      * `subtask_status` : dict containing values representing current status.  Keys are:

        'task_id' : id of subtask.  This is used to pass task information across retries.
        'attempted' : number of attempts -- should equal succeeded plus failed
        'succeeded' : number that succeeded in processing
        'skipped' : number that were not processed.
        'failed' : number that failed during processing
        'retried_nomax' : number of times the subtask has been retried for conditions that
            should not have a maximum count applied
        'retried_withmax' : number of times the subtask has been retried for conditions that
            should have a maximum count applied
        'state' : celery state of the subtask (e.g. QUEUING, PROGRESS, RETRY, FAILURE, SUCCESS)

    Sends to all addresses contained in to_list that are not also in the Optout table.
    Emails are sent multi-part, in both plain text and html.

    Returns a tuple of two values:
      * First value is a dict which represents current progress at the end of this call.  Keys are
        the same as for the input subtask_status.

      * Second value is an exception returned by the innards of the method, indicating a fatal error.
        In this case, the number of recipients that were not sent have already been added to the
        'failed' count above.
