Summary:
These are all essentially no-op changes which allow for nose-style (or pytest-style) test discovery.
With this patch, you can use any of these methods to discover and run tests under `caffe2/python`:
```
python -m unittest discover -p '*test*.py' caffe2/python/
python -m nose caffe2/python/
python -m pytest caffe2/python/
```
Future work:
* Get all of the tests to pass
* Some seem to be testing operations which don't have GPU implementations
* I get a segfault unless I set `CUDA_VISIBLE_DEVICES=0`
* Some tests are flaky
* Allow test discovery throughout the whole project (e.g. the `experiments/` dir)

Summary:
The current optimizer code in c2/python has the following issues:
(1) the optimizers in sgd.py cannot config per param-blob optimizer;
(2) sgd.py is a bad file name. optimizer.py is a better name;
(3) layer_model_helper.py has another set of optimizer code (which supports per param-blob optimizer)
This diff did the following
(1) create optimizer objects so that we can config per param-blob optimizer and that are also compatible to the existing optimizer code
(2) the new optimizer code are much more modulized
(3) move the optimizer code to file with better name (optimizer.py)
(4) replace the optimizer imports in the existing code
will do in next diffs
(1) optimizers with structured parameters for dper2
(2) get rid of the optimizer code in layer_model_helper.py
