The `.weights` attribute and `TrainableModel` no longer exist; handling both model types now makes the example much more complex and prohibits usefulness.

Additionally:
- Fix backticks in pydoc.
- Rename "fields" to "attributes" in pydoc.
- Replace federated_value with more preferred federated_eval.
- Replace collections.namedtuple usage with attr.s classes.
- Improve determinism for unittests.

The predominant usage was to obtain the `tff.learning.ModelWeights` from a model. Going forward code should use the `tff.learning.ModelWeights.from_model()` to do this.

Remove the `tff.utils` package now that it contains nothing.

Remove `tff.utils.assign`. This is trivially replaced with
`tf.nest.map_structure` calls.

Do not use or import the ABCs from `collections`, this is deprecated since Python 3.3, and in 3.9 it will stop working. These ABCs have moved to 'collections.abc' and should be used from this package.

(1) use skip_multi_gpu decorator or 'nokokoro' flag until we fix `dataset.reduce` issue in general
(2) update simple_fedavg client training to be compatible with our multi-gpu simulation recommendation.

Refactor `forward_pass` in `simple_fedavg` to be compatible with tff.learning. Clean `simple_fedavg` test to clearly distinguish `tff.learning.Model` and the standalone wrapper.

Remove the dependency on sample_batch in simple_fedavg. The standalone model wrapper is simplified and compatible with the recent change in keras and `tff.learning.Model`.

Migrates `cmp` arguments in attr.s() to `eq` and `order` arguments:
1. If `cmp=False`, replacing it with `eq=False`.
2. If `cmp=True`, replacing it with `eq=True, order=True`.

To modify the code, we can modify how client computes in "client_update", and modify how server computes in "server_update".
