* fix unit test for sqrt op
From the error logging:
[idx, grad, grad_estimate] are:
[[ 146. 0.5 0.45776367]
[ 147. 0.5 0.45776367]
The gradient == 0.5 is correct, which means the SqrtOp and its gradient is doing right job. (Because y = sqrt(x), loss = y^2/2 = x/2, and then d(loss)/dx = 1/2 = 0.5; )
The test failed because of numerical problem of grad_estimate (in unit test). It can be because the step_size is small, and float precision is not high (when there are multiple elements in the tensor, we do sum(y^2) to compute loss)
This diff
- increase the step size, and also move the test cases to be further away from 0 (where sqrt(x) is not well defined) to be safe :)
- also clean up, and merge the test case for inplace Vs. non-inplace
Tested with:

* Update GitHub upstream to 771fcb3455
* move sparse hash unique ops to OOS and add unit tests
- move the SparseHash version to OOS, since 'sparsehash' is already deps of caffe2 OOS: https://fburl.com/arssw4n1
- The 'SparseHash' engine is also being used in OOS, so the SparseHash version shall be in OOS to reduce confusion: https://fburl.com/o5ea7ah2
- fix the CUDA UniqueOp for the case when batch is empty.
- add unit test
* group_norm_op for caffe2
This is the cuda op for Group Normalization (GN): https://arxiv.org/abs/1803.08494
This code implements GN in one op that computes Y=gamma * (X-mu) / sigma + beta and also its gradients. It is expected to have minimal memory consumption (similar to the BN op), without creating new blobs if GN were implemented as several ops (e.g., reshape, norm_mean/std, affine_channel).
* Resubmit D7405233: disappeared in D7464958
OOS publish causes the op missing -- however, test was still there
* [c2] add sparse hash engine for cuda unique op
The SparseHash version of UniqueOp copy input tensor to CPU, and make use of sparse hash map to get unique output, and then copy back to GPU.
* [dper][gpu] enable unit testing gpu trainer for sparse nn
to debug the GPU trainer using mock data in unit test.
make it easier to develop GPU trainer for new models.
* Reuse Gloo context for Synchronize() calls
Previously we were creating (and leaking) the Gloo context on each call to Synchronize(). Now only run the common world op and create the barrier net once, then run the barrier net on each Synchronize() call. Since timeout is associated with the Gloo context, assert that the timeout is fixed instead of trying to handle the complexity of multiple timeouts (and associated contexts).

* [GanH]: enable diagnose within model

* Add `net_transformer_fun` option to DPM
This callback allows for various transformations to be made to the
model after gradient operators have been added. The immediate motivation for
this is to allow transformations such has "checkpoint-and-recompute" which
allow trading off memory for additional compute.
Adding several callbacks like this has made DPM's API less than ideal at this
stage. However, I could not find any reasonable alternative.

* Check mappings ONNX -> Caffe2 bear the same argument names
When adding an extra arg to an input ONNX op, if it's not supported in Caffe2, the exporter would just silently pass it to NetDef and ignore it in the implementation. It's pretty error-prone. Caffe2 also has an OpSchema description and we can enforce that all arguments explicitly appear in schema or listed explicitly in Caffe2.

Add test for C2 argument checking
* Some operators do not log arguments, which prevents argument checks.
Invite users to file an issue to fix the schema.
* Change Same as input type deduction to work for ops with multiple outputs
* change InferBlobShapesAndTypes definition to take vector ot pointers instead of unique_ptr. The function doesn't own the objects, so no need to pass smart pointers and that prevents calling the function with existing object, since the caller has to create unique_ptr, i.e. copy an existing object just to create the pointer
* switching order of std::move<unique_ptr> and uniqur_ptr.get
* adding comma
* [easy] allow empty tensor in cuda relu op
The diff has not enabled unit test of empty tensor, because MLKVersion of ReluOp need extra work to support
* Make blob norm plotting work with distributed trainer when the old framework is used

Added a caffe2 math sum operator so that it takes integers (only int32)
Changed the SumFloatIter to SumGenericIter so that it takes >1 types.
Added a sumElementInt operator
This code introduces a new class for exporting decoder step (ensemble) models trained with fbtranslate pytorch to Caffe2 models via ONNX, for the purpose of use in "component beam search" being developed concurrently in C++ by @juancarabina.
This is required to support placeholder/decorator ops which does not have operator schema. Note that the change is made in such a way that it is a no-op if placeholder Ops are not used.
Changes:
1. Since the placeholder ops always run on CPU, added a utility to infer placeholder ops blob devices.
2. Placeholder op's input/output blobs should be on CPU as well. This change takes care of dealing with output blobs - i.e. use blobs on CPU.
3. Added a Unit test - test_inject_copy_placeholder_ops
