    [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.

    [ml] Adds syntactic sugar for map with single broadcast element. Rewrites the optimization
framework to to consolidate the loss function.
    Adds closure cleaner to convenience functions on RichDataSet
    Removing regularization from LossFunction and making it part of the optimizer.
