Motivation
Related PR: open-mmlab/mmdetection#6974
Setting num_threads of OpenCV to 0 and
mp_start_methodtoforkcan speed up the overall training process. This PR allows user to configure these values in configs.However, I've run multiple experiments which showed that restricting MKL and OMP threads rather slows down the training. Therefore, this PR does not implement relevant configuration.
