Framework 5.3 added support for Apache HttpClient 5 to WebClient. We should add corresponding support in Spring Boot. I think that's some dependency management and some auto-configuration to create an HttpComponentsClientHttpConnector when it's on the classpath (and Jetty and Reactor Netty are not).
