This work was originally done by @ikavgo in Tanzu RabbitMQ.
Similarly to internal exchanges, that have restrictions on what applications can do with them,
and virtual hosts that have deletion protection in 4.x, this introduces a deletion protection concept for queues.
This relies on a map property all queues already have, so no schema migrations are necessary.
