/**
 * Extensible delegation token support for the S3A connector.
 *
 * Goal: support multiple back end token issue/renewal services, from
 * "pure client side" session tokens to full "Kerberos auth".
 *
 * It is intended for internal use only; any external implementation
 * of {@link org.apache.hadoop.fs.s3a.auth.delegation.AbstractDelegationTokenBinding}
 * must consider this API unstable and track changes as they happen.
