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.

* CORS headers removed because browsers should not interact with API directly
* Updated error handling to return expected content-type for JSON error messages
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
This works in conjunction with the new SMS provider stub [^1].
Local testing:
- Run the migrations to add Reach as an inactive provider.
- Activate the Reach provider locally and deactivate the others.
update provider_details set priority = 100, active = false where notification_type = 'sms';
update provider_details set active = true where identifier = 'reach';
- Tweak your local environment to point at the SMS stub.
export REACH_URL="http://host.docker.internal:6300/reach"
- Start / restart Celery to pick up the config change.
- Send a SMS via the Admin app and see the stub log it.
- Reset your environment so you can send normal SMS.
update provider_details set active = true where notification_type = 'sms';
update provider_details set active = false where identifier = 'reach';

Note that the new base class doesn't include a bespoke feature we
had here: 'log_on_worker_shutdown'. We've agreed it's reasonable
to remove it for now as it was introduced many years ago and its
use case is unclear - we can always add it back if needed.
In response to: https://github.com/alphagov/notifications-api/pull/3305#pullrequestreview-726672421
Previously this was added among the public /v2 endpoints, but it's
only meant for internal use. While only the govuk-alerts app would
be able to access it, the location and /v2 URL suggested otherwise.
This restructures the endpoint so it resembles other internal ones.
We can define the API properly in future work. I've used a separate
blueprint from "broadcasts" since this API is purely internal, and
it's helpful to make it clear it's specific to govuk-alerts.
See https://github.com/alphagov/notifications-utils/pull/878 for
details.
Changes we had to make for our app and tests to work correctly
after the dependency updates:
1. Update emergency alerts polygons test because we changed
how exact we are with locations of the points on the map.
2. Use Flask's g object to set additional request attributes
So far we have been storing them in _request_ctx_stack which is
an innard for Flask's request context.
Because of major update to Werkzeug dependency, which Flask relies
on, the way we were using it stopped working, so we had a new
way to set those values.
The way we set those values now, by using g object, seems to also
be favoured in Flask documentation:
