POWERDNS: Map dnscontrol Tags to powerdns Variants

[pefeigl]

Map example.com!internal to example.com..internal for the relevant pdns HTTP API calls.

I hope this is ok, I've tested it locally, it seems to work fine.
I am unsure what to do about the function EnsureZoneExists in file providers/powerdns/dns.go line 67, it only gets the domain name, I don't understand how to access the tag from it, to ensure the right variant name is calculated.

That's an interesting point! You would need to change the signature of EnsureZoneExists() to include a tag. You can include that here or in a separate PR.
