[dns-operations] TLDs allowing zone transfers

FYI, all of the ICANN contracted zones are supposed to provide zone
files.  For most of the new TLDs, you get it through https://czds.icann.org/en
where the requests are manual, but once you have access you can download
the file automatically.  Annoyingly, most expire access after 90 days so
you have to keep asking.

Most old gTLDs require a separate application that you e-mail to them and
they send you FTP credentials, but those work permanently.  A few of the
old TLDs have moved to czdap including pro, cat, coop, and museum.

The .us TLD provides access on application, .se provides public access,
.fr does on application if you are a French business.
