[feature] Add support for performing WHOIS lookups through local db

[DragnEmperor]

It would be better to have a local database for WHOIS lookup as the webservice approach has rate limitations. This will also ensure faster lookups without any dependency on internet connectivity.

These are the observations and information collected till now regarding the services provided by Maxmind and DB-IP:

We went through a different route of using the REST API. Maybe one day we'll come back to this. It depends on how the community will use this feature. For the moment I want to close this as I don't want new contributors to think we are actively working on this idea.

We can reopen the issue if we find out there's a real need for this.
