[registrars] Using IANA IDs

[Marcus Faure]

Hi all,

I propose that the registries implement the following change:

Instead of using proprietory registrar ids, standardized ids shall be used
both on protocol level (rrp/epp/reports etc.) and in the whois output.

The effect would be that for example CORE is IANA-15 in all registry
communication and not R135-LRMS at Afilias, R23-LROR at PIR and so on.
Especially transfers would become simpler, e.g. registrants will be less 
confused who they want to transfer their domain to,

Yours,
Marcus
