Make sure to insert new rulesets at the "end"

Dyn will still match them, even while they're empty before we've had a
chance to add the respons pools to them which is BAD and caused a
medium-size outage (thankfully not as bad as it could have been.) Ideally
we'd use publish=False and stage things, but that seems broken in the client
lib, there's no way to send publish=N. I also tried sending the
response_pool_ids as part of the create calls and response pool config if
one didn't exist, but neither of those routes worked :-(

Unsorted GeoValue.values can result in false diffs

Add DKIM to provider capabilities

Change str() to unicode() to avoid encoding problems

Fix handling of Cloudflare ALIAS updates

Extract _record_for from populate, use round trip in _apply_Update

fix logging for update/delete_pcent_threshold

This will ensure that we have exactly the same logic/behavior across the
board when turning records into content and prevent the :-( hack that was in
here before. It was missing the max(min, ttl) bit we throw everything else
through and this makes that consistent. Most importantly it'll prevent us
from having to fix bugs or make improvements in multiple code paths in the
future.

Remove unnecessary argument "cdn" from CloudflareProvider

Properly set filter rules for geo answers

Generate the zone name following the spec of Google Cloud DNS

Zone name must begin with a letter, end with a letter or digit, and only contain lowercase letters, digits or dashes, and be 63 characters or less.
For instance, a reverse zone of IPv6 may violate the spec on the first character and the length of the zone name.
