Review comment:
       'max_concurrency_value' is cooperating with the 'ParallelLauncher' which is running the worker thread is a thread_local variable,  so we need to make max_concurrency_value to be a thread_local variable too, then when different thread run 'ParallelLauncher', the different 'ParallelLauncher' can get different value of 'max_concurrency_value'
