title: Micronaut CORS allowedOrigins from evnironment variable
body: <p>I am currently building a microservice with Micronaut. now I want to add CORS support. At the moment my application.yml looks like this:</p>
  
  <pre><code>micronaut:
    application:
      name: gateway
    server:
      port: ${HTTP_PORT:8080}
      cors:
        enabled: true
        configurations:
          web:
            allowedOrigins:
              - http://localhost:8080
  </code></pre>
  
  <p>Is there a way to pass the allowedOrigins as an array from an environment variable?</p>
