To aid in tracking down the error that's causing
TestAccGoogleSqlDatabaseInstance_basic to fail (it's claiming an op
can't be found?) I've added the op name (which is unique) to the error
output for op errors.
* 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.
