Artem Bilan 6d192d8a57 Start version 5.1.0
* Upgrade to the latest dependencies
* Remove wrong JMS dependencies from the `spring-twitter-supplier`: there is really nothing to do with JMS
* Fix `CassandraTestContainer` to use new `CassandraContainer` class version: essentially, a deprecation of the previous one has led here
* Remove `apicurio` dependencies from the `spring-debezium-autoconfigure`.
We really don't need them for our logic and if there is a requirement in the target project, they can add such a dependency manually.
* Remove `commons-compress`, `avro` & `json` dependencies from the `spring-debezium-supplier`,
since they are just transitive dependencies for not any managed `apicurio` dependency
* Add explicit version for the `com.squareup.okhttp3:mockwebserver` since Spring Boot does not manage this dependency anymore
* Use Hazelcast `5.4.0` version since managed by Spring Boot `5.5.0` has a CP subsystem as a commercial offering only
* `@MockBean` to `@MockitoBean` in the `AbstractAwsS3ConsumerMockTests` since the first one is deprecated in Spring Boot, in favor of the second one
* Fix `ZeroMqConsumerConfiguration` to start `ZeroMqMessageHandler` from the `Flux` of function input
* Upgrade samples to the latest dependencies

= HTTP Request Function

This module provides an HTTP request function that can be reused and composed in other applications.
The `Function` uses the reactive `WebClient` from `Spring WebFlux` and is implemented as a `java.util.function.Function`.
This function gives you a reactive stream of `ResponseEntity` given a stream of request messages as the function a signature of `Function<Message<?>,ResponseEntity>`.
Users have to subscribe to the returned `Flux` to receive the data.

== Beans for injection

The `HttpRequestFunction` auto-configuration provides the following bean:

`httpRequestFunction`

You may inject this as `HttpRequestFunction`.

You can use `httpRequestFunction` as a qualifier when injecting.

Once injected, you can use the `apply` method of the `Function` to invoke it and then subscribe to the returned `Flux`.

== Configuration Options

All configuration properties are prefixed with `http.request`.

For more information on the various options available, please see link:src/main/java/org/springframework/cloud/fn/http/request/HttpRequestFunctionProperties.java[HttpRequestFunctionProperties.java]

== Examples

See this link:src/test/java/org/springframework/cloud/fn/http/request/HttpRequestFunctionTests.java[test suite] for examples of how this function is used.

== Other usage

See this https://github.com/spring-cloud/stream-applications/blob/main/applications/processor/http-request-processor/README.adoc[README] where this function is used to create a Spring Cloud Stream application to process HTTP requests.
