Description

`As a data scientist`
I want to call a Keras fit function from MADlib
`so that`
I can do distributed training of Keras models on Greenplum.

Proposed interface:

madlib_keras_fit(
    source_table            VARCHAR,
    model                   VARCHAR,
    dependent_varname       VARCHAR,
    independent_varname     VARCHAR,
    model_arch_table        VARCHAR,
    model_arch_id           INTEGER,
    compile_params          VARCHAR,
    fit_params              VARCHAR,
    num_iterations          INTEGER,
    num_classes             INTEGER,
    use_gpu                 BOOLEAN,
    validation_table        VARCHAR,
    name                    VARCHAR,
    description             VARCHAR
    )
