TensorBoard 1.7.0

The 1.7 minor series tracks TensorFlow 1.7.

Highlights

• (Beta) New Beholder plugin that shows a live video feed of tensor data during
  model training, by @chrisranderson. Caveat: only currently recommended for use
  where TensorBoard and TensorFlow share a local disk. See for details:
  https://github.com/tensorflow/tensorboard/tree/1.7/tensorboard/plugins/beholder
