Change `add_data_node` so that host parameter is required. If the host parameter is not provided, or is `NULL`, an error will be printed. Also change logic for how the default value for `port` is picked. Now it will by default use the port given in the configuration file. The commit update all the result files, add the `host` parameter to all calls of `add_data_node` and add a few tests to check that an error is given when `host` is not provided.
