> This means the user can configure a decimal value in replica
> example :
> {code:json}
> {"replica": 1.638, "node":"#ANY"}
> {code}
> This means a few things. The no:of of replicas in a node can be either 2 or 1. This also means that violations are calculated as follows
>  * If the replica count is 1 or 2 there are no violations 
>  * If the replica count is 3, there is a violation and the delta is *{{3-1.638 = 1.362}}*
>  * if the replica count is 0, there is a violation and the delta is *{{1.638 - 0 = 1.638}}*
>  * This also means that the node with zero replicas has a *more serious* violation and the system would try to rectify that first before it address the node with 3 replicas
