mod_rest: Support passing 'node' attr in disco#items queries
But only in queries. Should be fine if you can't include it in responses
since the requester should remember what node they asked for.

summary: Block s2s connections based on admin blocklists
...
This module uses the blocklists set by admins for blocking s2s
connections.
So if an admin blocks a bare domain using [Blocking Command][xep191]
via [mod\_blocklist][doc:modules:mod_blocklist] then no s2s connections
will be allowed to or from that domain.
