Deprecate Prefix & Suffix settings in favor of RegexRouter

AFAICT, the features of prefix and suffix can be done with a SMT

For example

```properties
transforms=TopicRename

transforms.TopicRename.type=org.apache.kafka.connect.transforms.RegexRouter
transforms.TopicRename.regex=(.*)
transforms.TopicRename.replacement=mirrored.$1.some-suffix
```
