Ensure tests that interact with RabbitMQ do not run in parallel

Since there are tests that restart RabbitMQ, every test that could
interact with RMQ must have this attribute on the class:

[Collection("IntegrationFixture")]

We would get random CI failures due to some tests executing that were
not part of this collection.
