-----------------------------------------------

Thanks for the suggestions  [~elgoiri]. I have updated the patch with unit 
tests for the ConfiguredFailoverProxyProvider class. I ran the test ~25 times 
it passed every time. With 50 iterations, it should be fairly resilient to any 
flakiness. Appreciate your review.

> Currently the dfs.client.failover.random.order is applied globally. If we 
> have a combination of router and non-router nameservice, the random order 
> should ideally be enabled only for the router based nameservice. This Jira is 
> to make this configuration per-nameservice so that this can be configured 
> independently for each nameservice.
