[spencergibb]

See spring-projects/spring-framework#34565

Probably exercising the ApiVersionConfigurer similar to spring-projects/spring-framework@e73dc37#diff-e0c82933740733fb6667aee4a2a0c2d2756c09e3e1975cd9bb6d16f1d62df663R81-R84

I've started a PR adding support for an API Version predicate in the Webflux Gateway Server.

There are some potential directions to go here (though not in a bean post processor) https://github.com/spring-cloud/spring-cloud-gateway/pull/3865/files#diff-2c30792f0889f666171777d9aa18f7947071571a9b0552f10aafb623c1bb2dbfR965-R983
