Review comment:
We can probably move this to the setup file
`madlib_keras_custom_function.setup.sql_in` and call that file here.

Review comment:
We can probably move these to to a common file as these values are used
by `MstLoaderInputValidator._validate_compile_and_fit_params()` and
`get_custom_functions_list()`.

Review comment:
Just a note, we currently support only 1 metrics, so we don't need to
iterate here, the loop is fine too. Will leave it upto you, if you want to
change it, else this is good too.
