+ConfigureTransports was introduced in a newer version of

+<https://github.com/golang/net/commit/08b38378de702b893ee869b94b32f833e2933bd2>

+<https://github.com/prometheus/common/commit/b5c358997cbf126e8f8518cdc024c32da3996d48>

+It's somewhat unclear whether ReadIdleTimeout is absolutely required to
+work around the upstream issues with HTTP/2 mentioned in the codebase,
+however HTTP/2 can be disabled using enable_http2 if this is the case.
