* After moving some bunch of beans from the `@EnableBinding` to the
auto-configuration for proper conditional lifecycle we need to be sure
that all those support beans are registered for each child context as
it was before after parsing imports on the `@EnableBinding`.
This way add `search = SearchStrategy.CURRENT` for all the conditions
in the `BindingServiceConfiguration`
* Fix `TestSupportBinderConfiguration` to rely only on the `Binder`
instance created once in the parent level.
This way when we use an aggregated application, only the parent context
creates for us a `TestSupportBinder` and all the child contexts reuse it.
* Register `BinderFactory` only once in parent ctx
