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.

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