The changes are related to the patch. Initially the number of batches run per
inference is set to the default batch_size value of the mode, which is reported
to the user through rte_ml_model_info_get.
This patch adds support to specify the number of batches to be run per
inference. Hence, the default batch_size is replace with nb_batches values
specified by the user.
