Manage Service Catalog entries efficiently with the Service Definition JSON Schema

The Datadog Service Catalog is a centralized knowledge base for an organization's services, enabling collaboration, service governance, and incident response. The Service Definition JSON Schema helps create and update Service Catalog records efficiently by leveraging IDEs' capabilities such as autocomplete data in service definitions, automatic validation of service definitions, and posting service definitions to the Datadog Service Definition API. The schema also enables storing custom metadata in the `extensions` field, allowing teams to manage their Service Catalog records using existing tools and practices.
