Revert "Make NetworkScore public API"

This reverts commit a2c7b14efcdd8c29ac17eef93ac7663a0841de96.
It is not a clean revert because
I3e31e218b507140ccf440706c01da46762c57807 and
I446b46dacc3684dde7dcd2046c81fb5ef3e2cd31 were merged since,
so this patch makes sure not to cancel out the changes in
these two patches.
