Release v0.12.0

Major changes and bug fixes

• Added nGraph support for TensorFlow Variable Ops and optimizers to eliminate unnecessary copy of tensors between device and host memory during training iterations
  • Use the following build option to enable this feature: --enable_variables_and_optimizers
• Build option to enable Grappler based nGraph integration: --use_grappler_optimizer
• Bazel build script now uses grappler to connect nGraph to TensorFlow
• Added API to query cxx11_abi and the above build options: cxx11_abi_flag()
• Enhanced Grappler based graph rewriting
