Parameters for changing the weights in a balancer pool smoothly from a start weight and end weight over a period of time. Currently, the only smooth change supported is linear changing between the two weights, but more types may be added in the future. When these parameters are set, the weight w(t) for pool time `t` is the following: 

t <= start_time: w(t) = initial_pool_weights
start_time < t <= start_time + duration:
  w(t) = initial_pool_weights + (t - start_time) *
    (target_pool_weights - initial_pool_weights) / (duration)
t > start_time + duration: w(t) = target_pool_weights
