Artem Bilan 89cd8812c3 GH-195: Introduce ComponentCustomizer (#273)
Fixes #195 

* Introduce a `ComponentCustomizer` contract to be exposed in
the end-user configuration for particular bean type
* introduce a `@CustomizationAware` annotation to mark a component 
as customizable
* Introduce a `ComponentCustomizationBeanPostProcessor` as an auto-configured
bean to apply `ComponentCustomizer` to a matching `@CustomizationAware` (if any)
* Use `@CustomizationAware` in the `FileSupplierConfiguration`
and demonstrate `ComponentCustomizer` feature in its tests
* Move `config-common` to functions parent to make the mentioned auto-configuration
available for all the functions
* Remove some other duplicated dependencies from the affected poms
