This package implement weighted round-robin load balancing algorithm, inspired from nginx.
It's works by increase all current_weight by their respective weight, then choose backend which has the largest current_weight, after that the previously selected backend will reduce its current_weight by total_weight, and this process will repeat every Next method called.
In case you have 3 backend server A, B, C and its weight 2, 3, 2 the selected server will -> { B, A, C, B, A, C, B }
