Amazon MQ now supports HTTP based authentication for RabbitMQ brokers

Amazon MQ now supports the ability for RabbitMQ brokers to perform authentication (determining who can log in) and authorization (determining what permissions they have) by making requests to an HTTP server. This plugin can be configured on brokers running RabbitMQ 4.2 and above on Amazon MQ by making changes to the associated configuration file. To start using HTTP based authentication and authorization on Amazon MQ, simply select RabbitMQ 4.2 when creating a new broker using the m7g instance type through the AWS Management console, AWS CLI, or AWS SDKs, and then edit the associated configuration file. To learn more about the plugin, see the [Amazon MQ release notes](https://docs.aws.amazon.com/amazon-mq/latest/developer-guide/amazon-mq-release-notes.html) and the Amazon MQ [developer guide](https://docs.aws.amazon.com/amazon-mq/latest/developer-guide/working-with-rabbitmq.html). This plugin is available in all [regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/) where Amazon MQ RabbitMQ 4 instances are available today.
