Increase thread pool size and modify manager instantiation

Increased the scheduled thread pool size from 2 to 8 in the 'ObCrankerApplication.java' and adjusted the instantiation of 'OpenBookManager'. These adjustments aim to speed up concurrent task processing and optimize the manager's RPC client with additional parameters, thus potentially improving the overall app performance and functionality.
