Sebastien Deleuze 1f011467b8 Introduce Kotlin functional bean definition DSL

As a follow-up of the ApplicationContext Kotlin extensions, close to
the Kotlin functional WebFlux DSL and partially inspired of the
Groovy/Scala bean configuration DSL, this commit introduces a
lightweight Kotlin DSL for functional bean declaration.

It allows declaring beans as following:

beans {
	bean<Foo>()
	profile("bar") {
		bean<Bar>("bar", scope = Scope.PROTOTYPE)
	}
	environment({ it.activeProfiles.contains("baz") }) {
		bean { Baz(it.ref()) }
		bean { Baz(it.ref("bar")) }
	}
}

Advantages compared to Regular ApplicationContext API are:
 - No exposure of low-level ApplicationContext API
 - Focused DSL easier to read, but also easier to write with a fewer
   entries in the auto-complete
 - Declarative syntax instead of functions with verbs like registerBeans
   while still allowing programmatic registration of beans if needed
 - Such DSL is idiomatic in Kotlin
 - No need to have an ApplicationContext instance to write how you
   register your beans since beans { } DSL is conceptually a
   Consumer<GenericApplicationContext>

This DSL effectively replaces ApplicationContext Kotlin extensions as
the recommended way to register beans in a functional way with Kotlin.
