Support multiple parameters for get_info()
Presently get_info() method takes only one parameter. If the user wants multiple GETINFO queries, they have to call the get_info() method multiple times like, get_info('traffic/read') get_info('traffic/written') It will be better if the user can just call a get_info_map() method with multiple parameters which will return a dictionary/mapping of all the results. This can be something like, ret_val = get_info_map('traffic/read', 'traffic/written') and then ret_val!['traffic/read'] and ret_val!['traffic/written'] can be used to retrieve the expected values
