title: How do you save progress during a Keras Tuner run?
body: <p>I am currently shifting through a larger search space with Keras Tuner on a free Google Colab instance. Because of usage limits, my search run will be interrupted before completion. I would like to save the progress of my search periodically in anticipation of those interruptions, and simply resume from the last checkpoint when the Colab resources become available to me again.
  I found documentation on how to save specific models from a run, but I want to save the entire state of the search, including what was already tried and the results of those experiments.</p>
  <p>Can I just call <code>Tuner.get_state()</code>, save the result, and then resume from where I left off with <code>Tuner.set_state()</code>? Or is there another way?</p>
