Review Comment:
Yes, I was suggesting adding a new parameter, like
`dfs.client.failover.router.internal.proxy.provider` you named.
Creating a new class is also a good solution. I'm a bit worried though about
the update story for clients who are already using the existing class.
The new parameter approach makes the update backward compatible with
existing client configs.
