Remove 'fullyQualified' from host and domain names (#631)

* Remove 'fullyQualified' from host and domain names

We don't actually enforce that these are properly fully-qualified
(there's no dot at the end) and we specifically use the term "label
name" when talking about labels.

Note: this doesn't convert FQDN -> DN (et al) in at least two types of
cases:
1. When the term is part of the XML schema
2. When the term is used by some external system, e.g. SafeBrowsing API

* Add TODO to rename fields
