Describe what happened:
When you integrate ElasticSearch with the Datadog Agent, it will write the body of all ElasticSearch Traces into the metadata.

Describe what you expected:
As the body can contain sensitive information, it shouldn't write the body into the traces as default, like in every other HTTP Request. This behavior should be explicitly set.

Steps to reproduce the issue:

1. Integrate ElasticSearch with the Datadog Agent
2. Send some request to ElasticSearch
3. Go to "Traces" -> "your ElasticSearch Service"
4. Click on a request and go to "METADATA" and you will see the body of the request
