updating mock. It now wraps the calls to sync and reads config from configuration file. I believe it's better not to use the preprocessor directive, i.e. not to put any test code in the engine_tcp. I just call the mock in the test_allreduce file. It's a file purely for testing purposes, so it's fine to use the mock there.
