We should add deprecation warning of --gpu-ids and --gpus to indicate users that they are deprecated and useless. We should not delete them immediately.

Since MMDP does not support non-distributed multi-GPU training, --gpus in train.py lost its role, so it is removed, --gpu-ids is changed to --gpu-id, because only one GPU can be specified for non-distribution training and testing.
If the number of GPUs is more than 1, there will be an assertion error in MMDP because MMDP does not support the situation with more than one GPU.
