The expectation is this variable should only be set on EB worker environments.
This will only be added in the presence of the AWS_PROCESS_BEANSTALK_WORKER_REQUESTS environment variable.
Register a middleware that will handle requests from the Elastic Beanstalk worker SQS Daemon.

    # SQS Daemon sends requests over HTTP - allow and process them before enforcing SSL.

  else
    app.config.middleware.use(Aws::Rails::EbsSqsActiveJobMiddleware)
