Comment:

 I pushed an initial branch for this (and #21855) in my branch
 `bug21403_draft`.

 It handles everything from the point where the user requests an onion
 address, to picking HSDirs, fetching descriptors, storing them in the
 cache, looking them up, and retrying dir requests when needed. It doesn't
 do any introduction-related actions.

 Please check it out!
