Upgrade TensorFlow to 2.3 / Tensorflow.NET to 0.20

Hello,
I'm opening this issue for our discussion around migrating our implementation of Image Classification to TF.NET 0.20. It's release is imminent and wanted to have a public place for the discussion.

Cheers,
Jake

Hi @JakeRadMSFT, I'm so exciting to hear that ML .NET will upgrade its DNN module to align with lastet version of Tensorflow.NET. Current release is Preview 4 in NuGet. I'm working on fixing the last 3 examples, it will be pretty soon to release v0.20. We've already shipped tensorflow native 2.3 libraries include Windows, Linux and Mac as well as GPU version.

TF .NET v0.20 will bring a lot of new features, the some main things are EAGER MODE, tf.dataset data preprocess and Keras high level deep learning framework which is partially working.

Should we update tf document since the version of tf.net and tf runtime has changed.
