> Summary output table of fit writes out `model_arch_table` and `model_arch_id` columns which are used to find the model architecture to use in predict. Instead, we should also store the model architecture in the model table, so that the model is self sufficient during predict and is not dependent on another table.
> The reason for this feature is if the model_arch_table is dropped by accident, then all models trained so far will become unusable. A model must be self sustainable.
> Acceptance:
> 1. A column called `model_arch` must be created in `model` (output table of fit). It's ok to create it here and not the summary table.
> 2. Predict must use `model_arch` from `model` table, and not from the model_arch_table.
