This commit introduces a new optional feature in the chatter.
Users can request translation from the Google Cloud Translation API.
Documentation: <https://cloud.google.com/translate/docs#docs>
Adding the key in settings will instantly enable the feature for all
users of the database and consumption is not measured nor limited
by Odoo as it is natively supported using the Google Cloud Console.
Translation values are stored in the database to reduce cost as
much as possible. Therefore, translation values are automatically
garbage collected every 2 weeks to prevent database pollution.
