Description

We use NameNodeHttpServer#initWebHdfs from RouterHttpServer.
However, this relies on NameNodeHttpServer#getAuthFilterParams() which uses:

    String httpKeytab = conf.get(DFSUtil.getSpnegoKeytabKey(conf,
        DFSConfigKeys.DFS_NAMENODE_KEYTAB_FILE_KEY));

We should refactor this to be able to specify the keytab file.
