JdkHttpClientResourceFactory has dependency on org.eclipse.jetty

[j3graham]

in spring-web, org.springframework.http.client.reactive.JdkHttpClientResourceFactory makes use of the jetty LifeCycle class.

It would be good to be able to use JdkHttpClientResourceFactory with no extra dependencies.

This is in v 6.0

@rstoyanchev was the usage of Jetty's LifeCycle type in JdkHttpClientResourceFactory intentional? I think it can be replaced with a check for ExecutorService in destroy(), and call ExecutorService::shutdown if so.

No, it's most certainly an oversight.
