Revert "Make rate_correction_factor support hierarchical structure."

This reverts commit 2b43f549539d00bcab844bbc4f644e98505c453b.

Reason for revert:
I was trying to find out some unexpected performance loss in the current head.

For some reason, after rebase this CL seems to trigger higher loss than expected. From 64dfc92f to 2b43f54, the performance changes are:
      avg PSNR    ovr PSNR    SSIM
low   -0.006	  -0.131      0.236
mid    0.017	  -0.032      0.505

Cheng, could you please take a look at this issue? In the meantime, let's temporarily revert this CL for command testing on other threads. Thanks!
