> The method
> https://madlib.apache.org/docs/latest/group__grp__keras__setup__model__selection.html
> offers a way to setup for grid search for model selection.
> Currently this method is one-shot:  you create the table all at once from scratch.
> One improvement is to allow users to incrementally build up the model selection table via multiple calls to this function.  That is, if the output table already exists, then append to it and continue on with the numbering of the mst_keys from where it left off. 
> This will allow more flexibility for :
> e.g.,  1
> create different model params for model architectures
> e.g., 2
> use different learning rates for different types of optimizers, etc.
