Range queries don't transmit other headers on Requests

[srijan55]

Hi, I am using Cortex in FrontEnd only mode, talking to a prometheus service serving the queries. But I found that the roundtrip tripperware , which takes care of aligning and splitting queries, strips of any headers which I specify on my queries and hence they don't reach my prometheus service.
Are there known reasons for why this approach was chosen. I see that apart from OrgId all the headers are removed (including authorization headers)

Pretty sure we just didn't think about it.
The frontend was written for Cortex, then quickly modified to be usable against non-Cortex services.

Let me see if I can make a contribution for this.
