Postfix the existing config names with `-beta` for `servlet` and `jdbc`.
To avoid any risk that the config was explicitly enabled for an unrelated reason resulting in unexpected behavior when upgrading to the latest version.
Sometimes servlets will call another servlet by “resetting” the request object. This maintains the attributes previously set, including the span. We want to allow the trace to start if there’s no “active trace” even if there is a span attribute.
Disabled by default, and only creates a span if existing trace detected.
To enable all of them:
* System Property: `-Ddd.integration.servlet.enabled=true`
* Environment Variable: `DD_INTEGRATION_SERVLET_ENABLED=true`
(They have independent configs as well. If needed, view the source below.)
