`dns` — make DNS requests

The dns check makes a DNS request and checks the result.

Examples

Testing for an A record value:

[[dns]]
domain = 'millimeter.io'
class = 'A'
value = '159.65.215.200'

Testing for the lack of a value:

[[dns]]
domain = 'secret.millimeter.io'
class = 'SRV'
state = 'missing'

Using a specific DNS nameserver:

[[dns]]
domain = 'secret.millimeter.io'
class = 'SRV'
value = '192.168.34.43:8125'
nameserver = '127.0.0.53'
