> StochasticLoadBalancer has many knobs which user can adjust.
> It would increase productivity by allowing StochasticLoadBalancer to accept online configuration
changes.
> LoadBalancer already implements setConf(Configuration) method which reloads relevant
configuration parameters.
> We need to add updateMasterConfiguration() method to Admin which invokes the setConf()
method.
