      Description

      Delegation tokens are supposed to be exchanged in a secure authentication, for security concerns.
      For example, HDFS only distribute or renew a delegation token under kerberos authentication

      DelegationTokenAuthenticationHandler used by KMS + HTTPFS doesn't follow this now, and poses security concerns. Details in comments.
