Spark MLlib does not support optimizer as a plugin, since the optimizer
interface is private.

My team has a custom optimization routine that we would have wanted to plug
in as a replacement for the default LBFGS / OWLQN for use by some of the
ml/mllib algorithms.
However it seems the choice of optimizer is hard-coded in every algorithm
except LDA: and even in that one it is only a choice
