A Stateless GraphQL Execution Service
Each GraphQL Executor is a consumer in the consumer group ServerChannel.GQL_EXECUTOR_CONSUMER_GROUP.
That consumer group listens to the stream ServerChannel.GQL_EXECUTOR_STREAM.
When the group receives a message, redis delegates it to one of the consumers.
A consumer receives the request & the consumer then creates a standard GraphQL Response and publishes it back to the server that sent the message by reading the socketServerId in the message payload.
