Fixes#557
Allow for a `defaultCandidate` flag on a binder configuration that, when FALSE,
ensures that the binder does not interfere with the default configuration process.
Fixes#542
- add option for `autoCommitOnError`
- make `autoCommitOnError` follow the state of `enableDlq` - no need to suppress commits if messages will be sent elsewhere
Fixes#509
- prevent autoconfiguration from reducing the existing partition count and/or replication factor
Split `autoConfigureTopics` in two separate settings, one for `autoCreateTopics`
and one for `autoAddPartitions` (to existing topics)
Renamed `defaultMinPartitionCount` to just `minPartitionCount` on the Kafka binder
Add a flag for controlling topic autoconfiguration by the Kafka binder
Fixes#504
- introduces a new binder setting `autoConfigureTopics` that allows the user to disable the automatic creation of topics by the binder
Additional tests for partitioning
Adding missing documentation for `replicationFactor`
Fixes#495
Currently, `minPartitionCount` is available both as a binder default and as a consumer property.
It would be simpler if it only was a binder setting (seeing as it has effect only as a default).
Fixes#498
- Honour the retry settings from ConsumerProperties;
- Add an additional `enableDlq` option in KafkaConsumerProperties that enables forwarding failed messages to a DLQ topic.
In the context of trying to configure Rabbit, the docs mention that the Rabbit config properties be added under `rabbit`:
```
...
binders:
rabbit1:
type: rabbit
environment:
spring:
rabbit:
host: <host1>
...
```
however, the properties should be configured under `rabbitmq` as reference in the [Spring Boot Appendix A](https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html)
