      Description

      If LeaseRenewer#closeClient() is not called, LeaseRenewer keeps the reference to a DFSClient instance in dfsclients forever. This prevents DFSClient, LeaseRenewer, conf, etc. from being garbage collected, leading to memory leak.

      LeaseRenewer should remove the reference after some delay, if a DFSClient instance no longer has active streams.
