Documentation Considerations

• Add information to the existing ES forwarding topic on how to configure username/password inside the Log Forwarding API to forward logs to an external Elasticsearch instance.
  • We should add information on how to create a Secret, what fields inside the Secret are possible, and how to configure basic auth with either HTTP or HTTPs.
  • I saw that we have existing documentation for what fields are possible in the Secret and we need to adjust that since now, you are able to define username and password as additional fields. In that same sentence, we should also remove the "MUST" keyword since now you have some choice, so maybe we can reframe this a little bit and only talk about the possible fields and when they are important.
