Add support to access the hashMap in consistenthash.go

[sasathy1]

My use case: I am planning to store a bunch of containers as nodes in the hashring. Each container would look at the hashring and decide what operations to do based on its position in the hashring. In order to do this, I need to access the hashring itself.
And so, Is there any plan to return the hashmap in the struct of hashring in consistenthash.go?

The hashring package of npm gives access to the ring structure itself. I was hoping to find a similar implementation of hashring in go. Would it be possible for you to support this?

Thanks,
Sai
