Add BatchNorm support

System information

• 1.15 and 2.3:
• Are you willing to contribute it (Yes):

Describe the feature and the current behavior/state.
The problem is described in the mailing thread.

I have next problem: trying to repeat one of the modern CNN architectures on Java API. Most of them are using BatchNormalization as a popular layer with tf.nn.batchNormalization() op.

I trying to use old operands like BatchNormWithGlobalNormalization

I've used but got Exception in thread "main" org.tensorflow.exceptions.TFUnimplementedException: Op BatchNormWithGlobalNormalization is not available in GraphDef version 175. It has been removed in version 9. Use tf.nn.batch_normalization().
at org.tensorflow.internal.c_api.AbstractTF_Status.throwExceptionIfNotOK(AbstractTF_Status.java:99)

This was deperecated years ago, but we have it in 1.15 and 2.x APIs.

The possible solutions:

1. To implement all required stuff in Java Ops
2. Add gradients and contributions in TF Core (gradients and another stuff) if it's possible

Lesen Sie zunächst den verlinkten Mailing-Thread und vergleichen Sie die aktuelle Unterstützung der Java API mit tf.nn.batchNormalization(). Der Issue schlägt entweder vor, die erforderlichen Java Ops zu implementieren oder TensorFlow Core gradients und zugehörige Beiträge hinzuzufügen; daher müssen der erwartete Implementierungspfad und die Kriterien für den Abschluss zuerst geklärt werden.
