Unable to create certificate for `local.domain.com`

[amiryonatan]

Since version 1.2.1, we're getting an error:

Error: "local.domain.com" is not a valid domain name.

@amiryonatan The latest release uses an external npm package for determining validity of a domain name, and subdomains have been explicitly disallowed.

I'm not sure of the reason for this; see my comment here: #79 (comment)

The change also appears to have busted generating certs for "localhost". We are seeing the following error:

UnhandledPromiseRejectionWarning: Error: "localhost" is not a valid domain name.
