Release Description
This release completely overhauls the DNS challenge verification method.
The verification check now uses `aiodns` to check the nameservers of the TXT record. Each nameserver must be serving out the TXT record for verification to pass.
This significantly speeds up the DNS challenge verification since Let's Encrypt checks the domain's name servers (not Google's), and because each check is now done in parallel.
Using the Libcloud Handler with Route53, verification is now taking approx. 25 seconds whereas before it was taking upwards of 5 minutes.
