Change DNS records on modal to show simple names

[mikeshultz]

Show simple names in the CustomDomain modal. For instance, instead of showing a records like this:

shop.example.com CNAME fs-autossl.ogn.app.
_dnslink.shop.example.com TXT "dnslink=/ipns/example.ogn.app"

Show them like this:

shop CNAME fs-autossl.ogn.app.
_dnslink.shop TXT "dnslink=/ipns/example.ogn.app"

Not only are those accurate Bind records, but I think it's more common with DNS providers to enter in the simple names instead of the fully-qualified names.

@nick is this something you're working on or finished? If not, shall we move it to the backlog?

Backlog sounds good
