- This implements a few `TODO`s in the code around actually polling
nameservers for zone deletes. I found this necessary for changes
that were truing up missed DELETEs, and wanted to make a poll/
update_status call to verify deletion across a fleet of nameservers
when one was down.
- This originally failed in PowerDNS, because in older versions
that are still in all the distro repos, PDNS responded with a
NOERROR and empty answer section when it got a query for a zone
it knew nothing about. NEAT.

- NOTE: This increases timeout for functional tests and we maybe
shouldn't do that.
