FileContext HDFS implementation can leak socket caches

      Description

      As noted by Nicholas in HDFS-3359, FileContext doesn't have a close() method, and thus never calls DFSClient.close(). This means that, until finalizers run, DFSClient will hold on to its SocketCache object and potentially have a lot of outstanding sockets/fds held on to.
