DOMAIN_ELSEWHERE	registrar list of nameserver names

DOMAIN_ELSEWHERE() is a helper macro that lets you easily indicate that a domain's zones are managed elsewhere. That is, it permits you easily delegate a domain to a hard-coded list of DNS servers.

DOMAIN_ELSEWHERE is useful when you control a domain's registrar but not the DNS servers. For example, suppose you own a domain but the DNS servers are run by someone else, perhaps a SaaS product you've subscribed to or a DNS server that is run by your brother-in-law who doesn't trust you with the API keys that would let you maintain the domain using DNSControl. You need an easy way to point (delegate) the domain at a specific list of DNS servers.

For example these two statements are equivalent:

DOMAIN_ELSEWHERE("example.com", REG_NAMEDOTCOM, ["ns1.foo.com", "ns2.foo.com"]);

# ...is equivalent to...

D("example.com", REG_NAMEDOTCOM,
    NO_PURGE,
    NAMESERVER("ns1.foo.com"),
    NAMESERVER("ns2.foo.com")
);

NOTE: The NO_PURGE is used out of abundance of caution but since no DnsProvider() statements exist, no updates would be performed.
