Parent issue: #951

Detail of Subtask

The testing parameters for this benchmark framework are stored in JSON files within the infinity/python/vector_benchmark/configs folder. run.py reads the user's input (name of the configuration file), locates the corresponding file, and passes it to the base_client's init for parsing. The parameters from the JSON file are then saved in the base_client class.
