Add root_data_dir to constructor of Resnet50KerasBenchmarkSynth and Resnet50KerasBenchmarkReal (#6259)

This is needed to avoid breaking benchmark execution if PerfZero provides more
Named arguments before  the benchmark class constructor is updated.

* Allow user to specify root_data_dir in the benchmark class constructor

* fix test benchmark_graph_1_gpu_no_dist_strat failing

- Failure only occurs when all 1_gpu tests are run
together with the error:
tensorflow.python.framework.errors_impl.NotFoundError:
Resource localhost/logdir:/tmp/cifar10_model/
N10tensorflow22SummaryWriterInterfaceE does not exist.
[Op:WriteScalarSummary] name: epoch_loss/

Another fix might be to generate a different model_dir
in the core code, but that has other draw backs such as
restarting from the checkpoint.

* Model_dir for all tests.

* Export benchmark stats using tf.test.Benchmark.report_benchmark()

* Fix python style using pyformat

* Add short imagenet tests (taken from seemuch)
- also rename to match go forward naming

* fix method name

* Update doc strings.

* Fixe gpu number.

* Add fill_objects

* fixed calling wrong class in super.

* fix lint issue.

* Add short imagenet tests (taken from seemuch)
- also rename to match go forward naming

* fix method name

* Update doc strings.

* Fixe gpu number.

* Added pass/fail and eager tests

* Add eager multi-gpu test.

* Add imagenet end-to-end accuracy test.

* Comment why ['foo']

* remove development test example.

- kears_cifar_main returns dict of stats after run.
- unit tests added for keras_common.
- lint issues fixed in all 4 files.
