Manager for `ACMEServer` and `ACMETLSServer` instances. `certs` and `http_01_resources` correspond to `acme.crypto_util.SSLSocket.certs` and `acme.crypto_util.SSLSocket.http_01_resources` respectively. All created servers share the same certificates and resources, so if you're running both TLS and non-TLS instances, HTTP01 handlers will serve the same URLs!
