provider/powerdns: Add support for PowerDNS 4 API #7819
This adds support for the non-experimental API present in PowerDNS 4, while retaining support for 3.X, with minimal changes.
If the plan is to drop 3.X entirely, I don't mind fixing those two things up, but that's not a decision I wanted to make alone.
Ok, I have also tested this ran against out current test framework for PowerDNS :)
Thanks so much for the work here ! LGTM so merging
