…ion block attribute References: * hashicorp/terraform#20505 * hashicorp/terraform#20626 In Terraform 0.12, behaviors with configuration blocks are more explicit to allow configuration language improvements and remove ambiguities that required various undocumented workarounds in Terraform 0.11 and prior. As a consequence, configuration blocks that are marked `Optional: true` and `Computed: true` will no longer support explicitly zero-ing out the configuration without special implementation. The `ConfigMode` schema parameter on the configuration block attribute allows the schema to override certain behaviors. In particular, setting `ConfigMode: schema.SchemaConfigModeAttr` will allow practitioners to continue setting the configuration block attribute to an empty list (in the semantic sense, e.g. `attr = []`), keeping this prior behavior in Terraform 0.12. This parameter does not have any effect with Terraform 0.11. This solution may be temporary or revisited in the future.
