Description
Trying to configure redis transport in messenger component via both framework bundle configuration framework.messenger.transports.*.options and query parameters in DSN leads to drop of options defined in framework.messenger.transports.*.options.

How to reproduce

1. Configure messenger bundle as follows:

framework:
    messenger:
        transports:
            tasks:
                dsn: '%env(APP_REDIS_DSN)%'
                options:
                    stream: my.tasks
                    group: app
                    consumer: app
                    delete_after_ack: true

2. Define env variable APP_REDIS_DSN with query string

APP_REDIS_DSN=redis://localhost?dbindex=2

3. Start a consumer

bin/console messenger:consume tasks

4. As a result only dbindex=2 will be passed into redis Connection. Parameters from framework.messenger.transports.tasks.options are lost

Possible Solution
Replace this line with

parse_str($parsedUrl['query'], $queryOptions);
$redisOptions += $queryOptions;
