For better user experience expose a `RequestEntity<?>` as a root object
for evaluation context for `statusCodeExpression` execution
JIRA: https://jira.spring.io/browse/INT-4436
* Fix `IntegrationRequestMappingHandlerMapping` and
`IntegrationRequestMappingHandlerMapping` to implement a
`DestructionAwareBeanPostProcessor` to allow to register and
destroy HTTP endpoints at runtime, e.g. via `IntegrationFlowContext`
with the dynamic `IntegrationFlow`s
* GH-2464: WebFlux: Get rid of Mono.block()
Fixes https://github.com/spring-projects/spring-integration/issues/2464
The `WebFluxInboundEndpoint` resolves a `Principal` via `Mono.block()`
operation.
This is prohibited situation in the non-blocking thread, like Reactor
Netty
* Defer `Mono<Principal>` resolution to the message header via
deferring the whole `Message` creating via `flatMap()` operation on the
main `doHandle()` `Mono`
**Cherry-pick to 5.0.x**
* * Fix Checkstyle for the Reactive Spring Security testing utils static imports
* Add `defaultIfEmpty()`, when `exchange.getPrincipal()` is an empty `Mono`
JIRA: https://jira.spring.io/browse/INT-4462
When the HTTP request body is empty, the `HttpMessageReader` ends up
with the empty `Mono` which can't be evaluated to any reasonable value.
* Add fallback to `requestParams` when `Mono` for body is empty and
also when `payloadExpression` returns null
**Cherry-pick to 5.0.x**

Resolve class and leaf package tangles in:
- core (except DSL)
- file
- http
- move `StaticMessageHeaderAccessor` to root `integration` package
- move acknowledgment related classes to a new `acks` package
- move `MMIH` to `handler.support`, alongside argument resolvers, also `HandlerMethodArgumentResolversHolder`
- move `ErrorMessagePublisher` to `core`
- move `PatternMatchUtils` to `support.utils`
- move `MessageSourceManagement` to `support.management`
- remove direct reference to `MicrometerMetricsCapter` from `IntegrationManagementSupport`
- add new class `MetricsCaptorLoader`
- move `OperationsCallback` to inner interface in `RemoteFileOperations`
- move `HttpContextUtils` to `config`
* Simplify MetricsCaptor loading.
* Polishing

The WebFlux on the server side can deal with MVC `@Controllers` as well
without any Servlet environment.
* Enable `IntegrationGraphController` when we not only in the
Servlet environment, but also in the WebFlux
* Upgrade to SF-5.0.4 and fix WebFlux tests to meet the latest requirements
(https://jira.spring.io/browse/SPR-16337)
* Move `WEB_FLUX_PRESENT` to the `HttpContextUtils`;
deprecate it in the `WebFluxContextUtils`
* Mention WebFlux ability for the `IntegrationGraphController` in the
`graph.adoc`
* add `BodyExtractor` support for Outbound part
* add `ClientHttpResponseBodyExtractor` as identity function
* add XML configuration for the Inbound part
* document `BodyExtractor` and Inbound XML support
Rename `replyToFlux` property to the `replyPayloadToFlux`
Doc Polishing
Fixes: spring-projects/spring-integration#2300
To allow to consume a streaming HTTP response downstream expose
`replyToFlux` option on the `WebFluxRequestExecutingMessageHandler`.
This way the body of the HTTP response can be converted now to the
`Flux` for subsequent output message.
The option is `false` by default; can be changed to `true` in the `5.1`
JIRA: https://jira.spring.io/browse/INT-4350
Spring MVC and Spring WebFlux handles `ResponseEntity` via appropriate
`ReturnValue` handlers.
This way all the headers and status code are fully up to end-user.
The body is handled by the appropriate converter/writer as before
* Add `ResponseEntity` handling to the `HttpRequestHandlingMessagingGateway`
and `WebFluxInboundEndpoint`.
The logic mostly compy/pasted from the `ResponseEntityResultHandler`
JIRA: https://jira.spring.io/browse/INT-4358
* Parse response in the `WebFluxRequestExecutingMessageHandler`
in reactive, on demand manner.
* Add protected for empty response body in case of error
The `PollableChannelPublisherAdapter` is based on the poll model of the
`FluxSink` and iterate and poll downstream `PollableChannel` until
there is an item or `n > 0`.
Having `take(6)` we end up with the cancel from the downstream
`Subscriber` after the batch is filled, but at the same time we continue
to poll the upstream source because `n` is like `Long.MAX_VALUE`.
* The proper way to interact is check for the `!sink.isCancelled()`
as well.
This way cancelled `sink` won't "steal" data from other subscribers
Fix compatibility with the latest dependencies
* Upgrade to Gradle 4.1
* Upgrade as much dependencies as possible
* Fix MongoDB module to resolve deprecation in the latest driver
* Increase receive timeout in the `ResequencerTests`
* Restore generic argument for the method reference in the `ReactiveStreamsTests`
* Fix `WebFluxInboundEndpoint` for the compatibility with the latest Reactor API
JIRA: https://jira.spring.io/browse/INT-4315
Move Reactive components outside of HTTP module to the new WebFlux one,
including XSD, tests and documentation
Make an appropriate polishing for the `http.adoc` with cross-link
to the `webflux.adoc`
Exclude transitive `spring-webmvc` for the `spring-integration-webflux`
