Domain expiration monitoring

As an extension of SSL expiration monitoring, it would be helpful if Checkly could alert for upcoming domain registration expirations.

Potentially queriable via WHOIS, for example:

$ whois checklyhq.com | grep 'Expiry Date'

Registry Expiry Date: 2024-02-19T16:18:33Z
