`useLayerExtension` default The default setting for `useLayerExtension` now considers the `http_proxy` environment variable. When `http_proxy` is set, `useLayerExtension` will be off by default. If you use a `http_proxy` but would still like to make use of the Sentry Lambda extension, exempt `localhost` in a `no_proxy` environment variable. Fixes: #17804
