 - [#7317](https://github.com/thanos-io/thanos/pull/7317) Tracing: allow specifying resource attributes for the OTLP configuration.

We changed the protobuf of the QueryAPI, if you use `query.mode=distributed` you need to update your client (upper level Queriers) first, before updating leaf Queriers (servers).
