`guix substitute --substitute' dies on unreachable substitute server

Problem: When using multiple substitute servers, if one of the server istemporarily unreachable, `guix substitute --substitute' will throw anexception. Example (while bayfront server was down, attempting to builda package only available locally (emacs-dvc)):

Expected: Since multiple substitute servers are being used, rather thanbombing out on the first unavailable one, `guix substitute --substitute'(or any other command implicated with substitute servers) should simplywarn about it before attempting the next one.
Bonus point: `guix substitute --query' should also print a warningmessage that substitute server X couldn't be reached (it doesn't printanything about that right now, just skips to the next one).

Hi Maxim,
Your recent investigation bug#30290 [0] rings this bell:
http://issues.guix.gnu.org/issue/26833
If it appears the same issue, maybe we could merge them. WDYT?
