Artem Bilan 87e11d21f8 Fix CORS registration for IntGraphController
We fail with `NoClassDefFoundError` when we use `@EnableIntegrationGraphController`
in WebFlux env without Spring MVC.
Another issue that we don't register CORS for WebFlux

* Extract top-level package protected classes for MVC and WebFlux to register CORS
in the appropriate environment according classpath
* Adjust `HttpIntegrationConfigurationInitializer` and `WebFluxIntegrationConfigurationInitializer`
for native compatibility
* Add `@Indexed` for `@MessagingGateway` for indexer support in Spring Boot and Spring Native

**Cherry-pick to `5.4.x` & `5.3.x`**

Checking out and Building

To check out the project and build from the source, do the following:

git clone git://github.com/spring-projects/spring-integration.git
cd spring-integration
./gradlew build

NOTE: While Spring Integration runs with Java SE 6 or higher, a Java 8 compiler is required to build the project.

If you encounter out of memory errors during the build, increase an available heap and permgen for Gradle:

GRADLE_OPTS='-XX:MaxPermSize=1024m -Xmx1024m'

To build and install jars into your local Maven cache:

./gradlew install

To build api Javadoc (results will be in build/api):

./gradlew api

To build reference documentation (results will be in build/reference):

./gradlew reference

To build complete distribution including -dist, -docs, and -schema zip files (results will be in build/distributions)

./gradlew dist

Using Eclipse

To generate Eclipse metadata (.classpath and .project files), do the following:

./gradlew eclipse

Once complete, you may then import the projects into Eclipse as usual:

File -> Import -> Existing projects into workspace

Browse to the 'spring-integration' root directory. All projects should import free of errors.

Using IntelliJ IDEA

To generate IDEA metadata (.iml and .ipr files), do the following:

./gradlew idea
