Purpose
=======
A field `use_google_gmail_service` has been used in stable to define
a mail server which use Gmail authentication.
But now that the fields `smtp_authentication` exists, we want to use it
to simplify the mail server form view. For the incoming mail server,
the field `server_type` will be used for the same purpose.
Add a new field to have the option to install `google_gmail` in the
main settings page.

Purpose
=======
Less secured apps are no longer supported by google, therefore, we need
to transition to the OAuth2 authentication system.
