RDS Aurora storage type back to default

[carloscastrojumo]

Description

As stated in the provider documentation for RDS storage_type:

Valid values are: "", aurora-iopt1 (Aurora DB Clusters); io1, io2 (Multi-AZ DB Clusters). Default: "" (Aurora DB Clusters); io1 (Multi-AZ DB Clusters).

However, when creating/modifying an Aurora DB Clusters with aurora-iopt1 and then go back to the default, ie: remove the value or set it to "", the provider does not actually revert back to aurora storage type.
