As discussed in #28681 this will refractor @soyuka implementation of redis using the redis stream features so we don't need to handle parking the messages ourself and redis is doing it for us.

Some interesting links about streams:

```

**GET**: Will use `XREADGROUP` to read the one  message from the stream
**REJECT**: Reject will just remove the message with `XDEL` from the stream as adding it back to the stream is handled by symfony worker itself
**ACK**: Will use the `XACK` Method to ack the message for the specific group

The sender will still be simple by calling the `XADD` redis function.
