多环境下MQ隔离方案探索

目前的Istio或其他类似Mesh技术都还不支持异步消息的路由控制。要实现异步消息隔离有两种可能的方案：
一种是用譬如Dapr这种全托管的Mesh方案，扩展实现异步消息的路由控制。
一种方案是直接广播，改造消息中间件，在接收以后根据环境标保留或丢弃。

new q: 是否可以采用这样一个方案，生产者在发送时携带透传当前环境的标签比如dev.local, 在集群消费模式下，消费者获取透传的环境标签，并与消费者当前环境判断，是否应该是当前消费者进行消费

The issue names no files, tests, or entry points. Begin by reviewing the existing message-routing and environment-isolation design, then compare the proposed producer-label and middleware-filtering approaches; done would require an agreed implementation design for isolating asynchronous messages across environments.
