    Update all the TPUStrategy examples to use the new v2 APIs, i.e.
    make_dataset_iterator -> experimental_distribute_dataset,
    make_input_fn_iterator -> experimental_distribute_datasets_from_function,
    unwrap -> experimental_local_results,
    experimental_run -> experimental_run_v2

    Update keras v2 optimizers to reuse coefficients which are shared across all updates, which reduces the total number of ops created by between 5% (for simple optimizers such as SGD and Adagrad) and 25% (for complicated optimizers such as Adam and NAdam). Separate copies are made for each device and dtype.

    The effect of this change on run time is fairly minimal since Grappler is expected to consolidate most of these ops; however it does improve graph construction time.
