Force replacement on illegal transition

We get errors similar to this from time to time:

Error: Altering topic configuration from `delete` to `compact` is not supported. Please create a new topic with `compact` policy specified instead.

Terraform should be able to detect that a resource needs to be recreated rather than updated.

I believe the error message is specific to Confluent Cloud. See "Important Note" in https://docs.confluent.io/current/cloud/using/broker-config.html

I was wondering if we could do something similar to dry-run in cloud: https://docs.confluent.io/current/cloud/cli/command-reference/ccloud_kafka_topic_update.html To detect if the config change is valid. If it’s just that one setting we could just special case it in the provider. ---- Robert Jordan

This might be possible to do, by issuing an AlterConfigs request with validate_only set during the plan phase.
