ref(rules): Add delayed_rules queue (#69808)

Add a new queue `delayed_rules` for the "slow" condition alerts celery
task as per [this
documentation](https://www.notion.so/sentry/RabbitMQ-0b28fcb3a2174969b3c134d66550cb6c#e9973d5eb4aa4745ae78f5b88f9f4c9b).
I also submitted an ops request to add workers to this. Nothing is
hooked up yet so this isn't running.
