> Router should have the ability to to auto msync to a nameservice. And it can
> ensure router periodically refreshes its record of a namespace's state.
> Different from HDFS-17027, this is controled by router itself without
> configuring with AbstractNNFailoverProxyProvider.
> And HDFS-16890 maybe lead to many read requests into active NN at the same
> time.
> This PR provides a new way to implememts auto msync in Router.
