title: How to enable Cloud Firestore Native Mode using API / command line?
body: <p>I'm writing a script for setting up a Google Cloud project and I'd like to use Firestore. A new project, however, is by default in <a href="https://cloud.google.com/datastore/docs/firestore-or-datastore" rel="noreferrer">Datastore mode</a>. </p>
  
  <p>Switching to Firestore can easily be done using the web interface in the cloud console but I'd like to automate it. Is there any API or command line tool (gcloud? firebase?) for enabling it?</p>
