If a querier sees a "stats" parameter in the query request, it will attach important information about the query execution to the response. But currently, even if an user sets this value, the Query Frontend will lose this value in its middleware/roundtrippers. This PR fixes this problem by properly encoding/decoding the requests in QFE.

This PR fixes this problem by properly encoding/decoding the requests in QFE. Moreover, this PR also fixes the problem where Thanos does not know about the field "peakSamples" in the stats response from Prometheus. This field was added a while ago, but the protobuf on thanos side was never changed.
