doc: dns.resolve wrong callback addresses argument description

[MrQubo]

The dns.resolve(hostname[, rrtype], callback) description says:

The callback function has arguments (err, addresses). When successful, addresses will be an array.

But it's not true for SOA record.

dns.resolve documentation:
https://nodejs.org/docs/latest-v6.x/api/dns.html#dns_dns_resolve_hostname_rrtype_callback

SOA returns objects. Should be an easy doc addition.

Any update. What exactly needs to be done.

I would like to work on this one. Feel free to make me an assignee on this so others will know I am working on it. I will update the DNS module docs.

I see that the dns.resolveSoa() method documents the object correctly. Should that information be copied to the dns.resolve() documentation, or should it just point users to dns.resolveSoa() to explain the SOA record object?

No need to duplicate that information, just point (link) to it.
