Description
According to the documentation, Redis should be configurable using the options object, but this seems not to work.

How to reproduce

framework:
  messenger:
    transports:
      mytransport:
        dsn: "redis://localhost:6379"
        options:
          stream: "stream-name"
          group: "worker-group"
          auto_setup: true

Messages should be posted into the stream-name stream, and consumed using worker-group group. However, messages are posted into messages stream, and consumed using symfony group name - you can check this on redis-cli: XPENDING messages worker-group yields "NOGROUP No such key 'messages' or consumer group 'worker-group'".

Using querystring parameters to configure the same options works just fine.
