[GitHub] flink pull request: [ml] Rework of the optimization framework

    [ml] Rework of the optimization framework

    This PR reworks the current optimization framework to make the regularization part of the optimization algorithm. Furthermore, it consolidates the `LossFunction` by defining a common interface for loss functions. The `GenericLossFunction` allows to construct loss function by specifying the outer loss function and the prediction function individually.
    
    Additionally, this PR introduces some syntactic sugar which makes programming with broadcast variables easier.
