   @nudles 
   
   I have locked versions of nccl 2.4.8 and mpich 3.3.2, because it is possible that newer
versions of dependencies may have API change in the future
   
   After including nccl and mpich, the build can be done with -DUSE_DIST=ON.
   
   There is other problem in conda build due to the inexistence of conda dnnl, but I am not
going to add dnnl in this PR. Therefore, I temporary use -DUSE_DNNL=OFF. 
   
   So the purpose of this PR is just to add nccl 2.4.8 and mpich 3.3.2 in conda and turn on
-DUSE_DIST=ON
