title: Use introspection query without authentication in graphql-spring-boot-starter
body: <p>Using the graphql-spring-boot-starter library <a href="https://github.com/graphql-java-kickstart/graphql-spring-boot" rel="noreferrer">https://github.com/graphql-java-kickstart/graphql-spring-boot</a>, is it possible to secure all requests but allow only the graphql introspection query with authentication?</p>
  
  <p>The project has enabled Spring security to use OAuth2 so every request is secured.</p>
  
  <p>Thanks for any hint or help.</p>
