Recognize Consumer<ServerBuilder> beans for spring autoconfiguration

[anuraaga]

I think it's useful to be able to customize with spring without using custom types, for example to allow creating a plugin module that just configures a server without needing to worry about armeria-spring. It's sort of similar to how Spring supports both custom annotations and javax.inject annotaions.

Idea came up in openzipkin-contrib/zipkin-storage-kafka#38
