Issue connecting to Google Cloud SQL with Cloud Shell
<p>When I try to connect to Google Cloud SQL via the Cloud Shell, I get the following error:</p>

<pre><code>gcloud beta sql connect mysql-1 --user=root
ERROR: (gcloud.beta.sql.connect) You do not have permission to access instance [mysql-1]: The client is not authorized to make this request.
</code></pre>

<p>I am not sure what permission is required to grant this access.</p>
