Configure ResourceUrlProvider in WebFlux and resource chain infrastructure [SPR-17433]

[spring-projects-issues]

Brian Clozel opened SPR-17433 and commented

Unlike what the reference documentation states, the default Spring WebFlux configuration does not provide a ResourceUrlProvider bean.

Also, the AppCacheManifestTransformer and CssLinkResourceTransformer both need a reference to the ResourceUrlProvider when dealing with absolute links. This needs to be configured during the resource chain setup as the ResourceUrlProvider needs to be aware of the application context.
