## Description ## Function concatenate() from module mxnet.numpy will now be executed by oneDNN primitives as it is done in module mxnet.ndarray. Additionally concat from mxnet.ndarray will gain numpy fuctionality which is flattening input arrays when parameter dim=None. ## Checklist ## ### Essentials ### - [x] PR's title starts with a category (e.g. [BUGFIX], [MODEL], [TUTORIAL], [FEATURE], [DOC], etc) - [x] Changes are complete (i.e. I finished coding on this PR) - [x] Code is well-documented ### Changes ### - [x] Merge NNVM_REGISTER_OP(_npi_concatenate) with NNVM_REGISTER_OP(concatenate) ## Comments ## It was possible to merge both ndarray and numpy concatenate operators into one NNVM_REGISTER_OP, additional functionality was added to ndarray concatenate by this process. Performance tests from mxnet profiler with 10 warmup runs and 50 test runs of this operator are given below:  Numpy concatenate was about 9 times faster in those tests -- This is an automated message from the Apache Git Service.
