GH-677: Fix resetOffsets with concurrency

Fixes https://github.com/spring-cloud/spring-cloud-stream-binder-kafka/issues/677

The logic for resetting offsets only on the initial assignment used a simple
boolean; this is insufficient when concurrency is > 1.

Use a concurrent set instead to determine whether or not a particular topic/partition
has been sought.

Also, change the `initial` argument on `KafkaBindingRebalanceListener.onPartitionsAssigned()`
to be derived from a `ThreadLocal` and add javadocs about retaining the state by partition.

**backport to all supported versions** (Except `KafkaBindingRebalanceListener` which did
not exist before 2.1.x)

- * Interface for Kafka Stream state store.
- *
- * This interface can be used to inject a state store specification into KStream building process so
- * that the desired store can be built by StreamBuilder and added to topology for later use by processors.
- * This is particularly useful when need to combine stream DSL with low level processor APIs. In those cases,
- * if a writable state store is desired in processors, it needs to be created using this annotation.
- * Here is the example.
- *
- * <pre class="code">

- *     &#064;KafkaStreamsStateStore(name="mystate", type= KafkaStreamsStateStoreProperties.StoreType.WINDOW, size=300000)
- *	   public void process(KStream<Object, Product> input) {
- *         ......
- *     }
- *</pre>
- *
- * With that, you should be able to read/write this state store in your processor/transformer code.
- *
- * <pre class="code">
- * 		new Processor<Object, Product>() {
- * 			WindowStore<Object, String> state;
- * 			&#064;Override
- *			public void init(ProcessorContext processorContext) {
