Brief Summary

We need to remove the AMQP result backend as it was marked as deprecated in 4.0.

A deprecation message was printed for our users and therefore we can remove it.

Architectural Considerations

None

Proposed Behavior

The AMQP result backend will no longer work and an error will be presented to the user.

Proposed UI/UX

When the backend is initialized, an ImproperlyConfigured exception is raised with the following message:

The AMQP result backend has been removed in 5.0.
Please use the RPC result backend or choose another result backend.

This message will be removed in 6.0.
