As stated in the second generation pricing documentation:
> Second Generation pricing is composed of the following charges:
>
> Instance pricing
> Storage pricing
> Network pricing
> There is no choice of pricing plan.
cf. https://cloud.google.com/sql/pricing#2nd-gen-pricing
According to the referenced documentation, it is one week, not two months:
> You cannot reuse an instance name for up to a week after you have deleted an instance.
cf. https://cloud.google.com/sql/docs/mysql/delete-instance
* provider/google-cloud: Add maintenance window
Allows specification of the `maintenance_window` within the `settings`
block. This controls when Google will restart a database in order to
apply updates. It is also possible to select an `update_track` to
relatively control updating between instances in the same project.
* Adjustments as suggested in code review.
Cloud SQL Gen 2 instances come with a default 'root'@'%' user on
creation. This change automatically deletes that user after creation. A
Terraform user must use the google_sql_user to create a user with
appropriate host and password.
* provider/google Document MySQL versions for second generation instances
Google Cloud SQL has first-gen and second-gen instances with different
supported versions of MySQL.
* provider/google Increase SQL Admin operation timeout to 10 minutes
Creating SQL instances for MySQL 5.7 can take over 7 minutes,
so the timeout needs to be increased to allow the
google_sql_database_instance resource to successfully create.
