Currently we have dns-webservice module which exposes /.well-known/host-meta endpoint for XEP-0156. The problem is that because we can have context assigned to only single module the resulting URL is: dns-webservice/.well-known/host-meta which won't work. One possibility would be to move dns-service to root context, but this would block other modules.

The idea from the call: have additional module that would allow registration of the "well-known" providers and it would inject them to the root context.
