This changeset pulls in all of the notification_utils code directly into the API and removes it as an external dependency. We are doing this to cut down on operational maintenance of the project and will begin removing parts of it no longer needed for the API.

This deletes a big ol' chunk of code related to letters. It's not everything—there are still a few things that might be tied to sms/email—but it's the the heart of letters function. SMS and email function should be untouched by this.
Areas affected:
- Things obviously about letters
- PDF tasks, used for precompiling letters
- Virus scanning, used for those PDFs
- FTP, used to send letters to the printer
- Postage stuff

* Bump govuk-bank-holidays to cache holidays for next year.
Last year we had an issue with the daily limit cache and the query that was populating it. As a result we have not been checking the daily limit properly. This PR should correct all that.
The daily limit cache is not being incremented in app.notifications.process_notifications.persist_notification, this method is and should always be the only method used to create a notification.
We increment the daily limit cache is redis is enabled (and it is always enabled for production) and the key type for the notification is team or normal.
We check if the daily limit is exceed in many places:
- app.celery.tasks.process_job
- app.v2.notifications.post_notifications.post_notification
- app.v2.notifications.post_notifications.post_precompiled_letter_notification
- app.service.send_notification.send_one_off_notification
- app.service.send_notification.send_pdf_letter_notification
If the daily limits cache is not found, set the cache to 0 with an expiry of 24 hours. The daily limit cache key is service_id-yyy-mm-dd-count, so each day a new cache is created.
The best thing about this PR is that the app.service_dao.fetch_todays_total_message_count query has been removed. This query was not performant and had been wrong for ages.
We had a situation where the delivery-worker app instance was terminated before the job was marked as `in-progress`, presumably because the query to check the daily limits was taking too long to complete.
If the job was in progress the `check_job_status` task would have restarted the job.
Updating the status to in-progress sooner will help.
These tasks need to repeatedly get the same template and service from
the database. We should be able to improve their performance by getting
the template and service from the cache instead, like we do in the REST
endpoint code.
