Hide storage errors from users #7252
Description
Is your feature request related to a problem? Please describe.
As discussed in #6975 (comment)
cortex should not expose storage errors to users. Users should only get information they need to fix their requests.
Describe the solution you'd like
I'd like to be able to return a cortex internal error for all storage issues instead of a full detail error. And at the same time I believe it should be possible to enable detailed error for specific requests. Maybe by issuing a specific http header.
