Wrap Scroll execution with usingWhen and run cleanup through usingWhen callback to clean up scrolls state on success/on error/on cancellation.
Extract isEmpty(SearchHits) check into own method. Improve synchronization in ScrollState to prevent concurrent modification exceptions during read.

The ReactiveElasticsearchClient now support scrolling through large result sets issuing subsequent _search/scroll requests while emitting data on the outbound channel. Resources bound via their scrollId get freed on completion of the flux.
Original Pull Request: #231
Update documentation to cover newly added configuration options for the ReactiveElasticsearchClient.
Make sure to apply postFilter correctly and set a default limit for unpaged search requests.
Also fix some code format issues.
We now log HTTP requests and responses with the org.springframework.data.elasticsearch.client.WIRE logger for both, the HighLevelRestClient and our reactive client and associate a logging Id for improved traceability.
Configuration of connection/socket timeouts is now available via the ClientConfiguration.
Along the lines we also aligned entity handling to EntityOperations already common in other modules. EntityOperations centralizes how aspects of entities (versioning, retrieval of index name/index type) are handled.

ReactiveElasticsearchOperations is the gateway to executing high level commands against an Elasticsearch cluster using the ReactiveElasticsearchClient.
The ReactiveElasticsearchTemplate is the default implementation of ReactiveElasticsearchOperations and offers the following set of features.
* Read/Write mapping support for domain types.
* A rich query and criteria api.
* Resource management and Exception translation.
To get started the ReactiveElasticsearchTemplate needs to know about the actual client to work with.
The easiest way of setting up the ReactiveElasticsearchTemplate is via AbstractReactiveElasticsearchConfiguration providing
dedicated configuration method hooks for base package, the initial entity set etc.
@Configuration
public class Config extends AbstractReactiveElasticsearchConfiguration {
@Bean
@Override
public ReactiveElasticsearchClient reactiveElasticsearchClient() {
// ...
}
}
NOTE: If applicable set default HttpHeaders via the ClientConfiguration of the ReactiveElasticsearchClient.
TIP: If needed the ReactiveElasticsearchTemplate can be configured with default RefreshPolicy and IndicesOptions that get applied to the related requests by overriding the defaults of refreshPolicy() and indicesOptions().
The ReactiveElasticsearchTemplate lets you save, find and delete your domain objects and map those objects to documents stored in Elasticsearch.
@Document(indexName = "marvel", type = "characters")
public class Person {
private @Id String id;
private String name;
private int age;
// Getter/Setter omitted...
}
template.save(new Person("Bruce Banner", 42)) // save a new document
.doOnNext(System.out::println)
.flatMap(person -> template.findById(person.id, Person.class)) // then go find it
.doOnNext(System.out::println)
.flatMap(person -> template.delete(person)) // just to remove remove it again
.doOnNext(System.out::println)
.flatMap(id -> template.count(Person.class)) // so we've got nothing at the end
.doOnNext(System.out::println)
.subscribe(); // yeah :)
The above outputs the following sequence on the console.
> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
> Person(id=QjWCWWcBXiLAnp77ksfR, name=Bruce Banner, age=42)
> QjWCWWcBXiLAnp77ksfR
> 0

Convert spaces to tabs for pom.xml. Switch reactive dependencies to optional. Remove unused commonscollections property. Use managed versions for reactor and Spring dependencies.
Introduce WebClientProvider to avoid reinstantiation of WebClient instances. Introduce ClientConfiguration to encapsulate common Elasticsearch client configuration properties. Split ElasticsearchClients into RestClients and ReactiveRestClients to avoid mandatory dependency on WebFlux/Project Reactor. Adapt tests and code referring to WebClient creation.
Extract response body as byte array instead of Flux of DataBuffer to avoid chunking and to parse an entire response.
Encapsulate hostAndPort string used across configuration/HostProvider with InetSocketAddress. Add parser for InetSocketAddress.

Initial implementation of a ReactiveElasticsearchClient using WebClient to connect to cluster nodes.
ReactiveElasticsearchClient client = ElasticsearchClients.createClient()
.connectedTo("http://localhost:9200", "http://localhost:9201")
.reactive();
A HostProvider selects active nodes and routes requests.
client.index(request ->
request.index("spring-data")
.type("elasticsearch")
.id(randomUUID().toString())
.source(singletonMap("feature", "reactive-client"))
.setRefreshPolicy(IMMEDIATE);
);
This implementation provides the first building block for reactive Template and Repository support to be added subsequently.
Along the lines we upgraded to Elasticsearch 6.5.

* Move @Parent property recognition to ElasticsearchPersistentProperty
* Move type contraints for @Version and @Parent fields to ElasticsearchPersistentProperty to fail faster
* remove unused constant SUPPORTED_ID_TYPES from SimpleElasticsearchPersistentProperty
