[BUG] HTTP error 402 on Cloudsmith repositories, need to switch to novemberain.com mirror

[sylvainfaivre]

As of today, trying to download from the Cloudsmith repo results in :

E: Failed to fetch https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-erlang/deb/debian/dists/bullseye/InRelease 402 Payment Required

The cause is described in this issue from another project : balena-io/etcher#4034

And this announcement on the RabbitMQ Discord server :

Hey folks

Team RabbitMQ has noticed that after the Erlang 26.1 release there was a significant uptick in bandwidth usage on Cloudsmith. Very likely our account will hit a traffic quota early next week, and all downloads directly from Cloudsmith will be blocked.

There is nothing our team can do about it, we already get special deal terms from Cloudsmith.

However, there is an easy solution for you the users: simply switch to our mirrors instead of consuming Debian and RPM packages from Cloudsmith directly [1] [2].

These mirrors are maintained by Team RabbitMQ, have an almost 20 times larger traffic quota (that can be cheaply expanded, while overages on Cloudsmith are really expensive).

They have been in operation since early May 2023.

Please switch away from Cloudsmith and to these mirrors ASAP, otherwise, next week your package downloads will begin failing until September 30, 2023 when a new billing cycle starts.

https://rabbitmq.com/install-debian.html

The install-debian.html docs now point to two mirrors hosted on the novemberain.com domain.

I might make a PR about this in the next weeks.
