* Parent class for {@link Authenticator} implementations that support native protocol v1 authentication.
* <p/>
* Protocol v1 uses simple, credentials-based authentication (as opposed to SASL for later protocol versions).
* In order to support protocol v1, an authenticator must extend this class.
* <p/>
* We use an abstract class instead of an interface because we don't want to expose {@link #getCredentials()}.
*
* @see <a href="https://github.com/apache/cassandra/blob/trunk/doc/native_protocol_v1.spec">Native protocol v1 specification</a>
