Corrected target code since training parameter "learning_rate_decay" is unsupported for the backend Caffe2.

Modified CNNTrainer.ftl: improved way to enter the optimizer parameters in template since the support checker for training parameters is already implemented.
Corrected  order of training parameters in target files based on the modification.

CNNCreator.ftl: Modified path constants to make their value dynamic instead of hard coded during code generation. Modified methods save_net and load_net.

Fix for missing quotes in eval_metric value.

Add num_epoch and eval_metric training parameters to the CNNTrainer.ftl template and correct target code for corresponding test
