Rather than using the dnspython's facilities and defaults to create the
queries, use the isctest.query.create function in all the cases that
don't require special handling to have consistent defaults.
All these setup files only use copy_setports function which can be done
with jinja2 templates instead -- simply by renaming the .in files to
.j2, without any other changes. The pytest runner will render these
templates during test setup without any need for an additional script.
This change adds a "none" parameter to the query-source[-v6]
options in named.conf, which forbid the usage of IPv4 or IPv6
addresses when doing upstream queries.
