Move release notes from rabbitmq/rabbitmq-website Keeping them in this repo might encourage more people to update them as changes are merged, and simplify release automation a bit. So let's try it. Per suggestion from @gerhard.

RabbitMQ `3.9.1` is a maintenance release in the `3.9.x` release series. [This is what changed since v3.9.0](https://github.com/rabbitmq/rabbitmq-server/compare/v3.9.0...v3.9.1).
Please refer to the **Upgrading to 3.9** section from [v3.9.0 release notes](https://github.com/rabbitmq/rabbitmq-server/releases/tag/v3.9.0) if you are upgrading from a version prior to 3.9.0.
This release requires at least Erlang 23.2, and supports the latest Erlang 24 version, 24.0.5 at the time of release. [RabbitMQ and Erlang/OTP Compatibility Matrix](https://www.rabbitmq.com/which-erlang.html) has more details on Erlang version requirements for RabbitMQ.
