Google Drive Dropbox
Enabling a connection to Google Drive requires the creation of an OAuth 2.0 Client ID through the Google API dashboard.
Steps to Enable
Follow the steps at https://developers.google.com/identity/protocols/oauth2 to create an OAuth 2.0 Client ID for your Avalon instance
Use the Client ID and secret in your Avalon site's settings.yml (see Upgrading Avalon 7.2 to Avalon 7.3 for config details)
Once configured, restart the app
Google Drive will now appear as a source in the "Open Dropbox" file picker in Avalon
