* Deprecated acme.crypto_util.Format in our effort to remove our
pyOpenSSL dependency
* achallenges.KeyAuthorizationAnnotatedChallenge, achallenges.DNS,
and achallenges.Other have a new field identifier, of type
acme.messages.Identifier. This should be used in place of the
domain field, which is now deprecated both as an attribute and
during object creation.
