New functions for DNS queries and PING

[dkr8toha]

I would like to have functions to check common DNS Records like

RETURN dns::query::a('surrealdb.com');

13.32.27.36

RETURN dns::query::mx('surrealdb.com', { detail: true } );

[ { prio: 1, name: "aspmx.l.google.com" }, ... ]

or even to use a server:

RETURN dns::query::a('surrealdb.com', { servers: '8.8.8.8, 8.8.4.4' });

And if possible also a ping function for a quick healthy check:

RETURN sys::ping(dns::query::a('surrealdb.com'));

The main reason for using is a validator on a company.homepage field ...

DEFINE FIELD homepage ON TABLE company TYPE string
  ASSERT sys::ping(dns::query::a($value));

Or one may define it as a future:

CREATE company SET
    homepage = "surrealdb.com",
    homepageAvailable = <future> { sys::ping(dns::query::a(homepage)) }
;

What do you think?
