Register the global bdevperf object as an I/O device by spdk_io_device_register(). Create and destroy I/O target groups asynchronously by using spdk_for_each_thread() and spdk_for_each_channel(). spdk_for_each_thread() and spdk_for_each_channel() serialize the execution among multiple threads, and any lock is not necessary. Additionally, for bdevperf_submit_on_core() and bdevperf_stop_io_on_core(), replace for their loop + event call by spdk_for_each_channel() and rename them by bdevperf_submit_on_group() and bdevperf_stop_io_on_group(), respectively. This advances the work to move bdevperf from core based to thread based.
