1. solved the previous delayed unit test file size is too large (1.7G+) and the unit test link time is too long problem problems
2. Unify all unit tests into one file to significantly reduce unit test execution time to less than 3 mins
3. temporarily disable stream_load_test.cpp, metrics_action_test.cpp, load_channel_mgr_test.cpp because it will re-implement part of the code and affect other tests
1. replace all boost::shared_ptr to std::shared_ptr
2. replace all boost::scopted_ptr to std::unique_ptr
3. replace all boost::scoped_array to std::unique<T[]>
4. replace all boost:thread to std::thread
Mainly change:
1. Fix the bug in `update_status(status)` of `PlanFragmentExecutor`.
2. When the FE Coordinator executes `execRemoteFragmentAsync()`, if it finds an RPC error, return a Future with an error code instead of exception.
3. Protect the `_status` in RuntimeState with lock
4. Move the `_runtime_profile` of RuntimeState before the `_obj_pool`, so that the profile will be
deconstructed after the object pool.
5. Remove the unused `ObjectPool` param in RuntimeProfile constructor. If I don't remove it,
RuntimeProfile will depends on the `_obj_pool` in RuntimeProfile.
