Description
In current implementation, no matter deep_supervision is used, the corresponding heads will be used. In addition, extra heads may be maintained, when deep_supr_num is less than the number of up sample layer - 1. It may also be related with Project-MONAI/MONAILabel#492
I planned to change it within #3265 , but it brought breaking changes (574fe60) and may make users' old weights cannot be used.
Therefore, here I open another ticker, and I will do a further enhancement.
