Describe

Move unittest test_optimizer_in_control_flow from CI multi_cards.

• Why do this? test_optimizer_in_control_flow.py needs to run in multi cards to test NotImplementedError. Here, move this test from RUN_TYPE=DIST in tests/unittests/CMakeList.txt, to use multi cards only on CPU not GPU to reduce CI time.
