      Refactors the aggregator and tff computation for hierarchical histogram. · 31d16fa2
      A. Unique TensorFlower authored 
      Changes:
(1) Replaces the old dp_query `CentralTreeSumQuery` with the updated one `TreeRangeSumQuery`. The updated query has several advantages:
    1) It easily supports different DP mechanisms (e.g. GaussianSumQuery,
    DistributedDiscreteGaussianSumQuery) by taking them as inner queries;
    2) `TreeRangeSumQuery` does not hard-code any clipping inside so it is
    composable with various clipping factories. To avoid DP error, it does norm
   checking inside to make sure appropriate clipping happens outside.
(2) Removes the type conversion from int32 to float32 before return in `discretized_histogram_counts`. Now the function outputs int32 tensors. This change is due to the type requirement of `HistogramClippingSumFactory`.
(3) Updates tff's dependency on tensorflow privacy to 0.7.0.

      Removes the non-negative enforcement in `enforce_consistency` because sometimes it introduces high bias.

      Returns second argument to binary operator in... · c84564db
      Keith Rush authored 
      Returns second argument to binary operator in create_binary_operator_with_upcast uncoerced in the case of type assignability to the first arg.

This change represents a slight relaxation in (static) semantics for create_binary_operator_with_upcast. Previously a binary operator with signature like:
```
<float32[?],float32[1]>
```
could not be constructed, though TensorFlow's shape assignability allows for a graph like this. This change allows for signatures such as the above to be represented in TF computation factory.

We do not, however, open the door to signatures like:
```
<float32[?],float32[1, 1]>
```
(though TF will generate graphs which represent it), since such a signature does not pass TFF's notion of assignability.

      Clean up and clarify `select_output_from_lambda` · f3ffe041
      Taylor Cramer authored 
      The `select_output_from_lambda` function previously had
surprisingly different semantics on outer-tuples from
nested tuples: outermost tuples or lists indicated a
structure of results, while inner tuples or lists
indicated paths to elements. No distinction was made
between tuples and lists.

This CL changes to use tuples for multi-index
selection paths and lists for selecting multiple
different values. This simplifies some call sites.

Includes test cleanup to remove outdated references
to "Federated" and to test the new selection abilities.
