This is a place for re-usable Saluki-only defaults.
Important: this is not a place where we should restate Datadog Agent schema-derived defaults. Defaults that flow from the Datadog schema are defined by codegen in the appropriate crate. We only want the definitive codegen defaults rather than restating values that can drift (see #1802).
