Changed format from yaml to plain python. The new py configuration file, when provided, must specialize the CHI node types defined in configs/ruby/CHI_config.py (moved from configs/ruby/CHI.py). This is required in order to setup the node->router bindings when the CustomMesh topology is used. See configs/example/noc_config/2x4.py (replaces configs/example/noc_config/2x4.yaml) for an example. --noc-config was also renamed to --chi-config, since the CHI node types can be fully specialized in the configuration file.
