Motivation: ACME, or Automatic Certificate Management Environment, supports responding to challenges via a TLS handshake. During this handshake, the TLS server must respond with a self-signed certificate that contain a special 'acmeIdentifier' extension. Modification: Add a method to `CertificateBuilder` for adding such 'acmeIdentifier' extensions, and include brief documentation on how to use it. Result: The pkitesting module can be used to experiment with the TLS-ALPN-01 ACME challenge method.
