Fix console nginx: use variable upstreams for resilient DNS resolution

Browse Source 
nginx crashes at startup if upstream hosts aren't resolvable yet.
Using 'set $upstream' + Docker's internal resolver (127.0.0.11)
defers DNS resolution to request time, so console starts even if
backends are still booting.
