Support JSF validation messages customizations

[yurem]

Current customization approach allows to override default labels. But it not allows to override JSF validation message. Java provides extensions support which allows to write custom ResourceBundle loader.

We can use [Resource Bundle as an Extension](https://docs.oracle.com/javase/tutorial/i18n/serviceproviders/resourcebundlecontrolprovider.html#register-service-provider). In this case we need to write small library which implements ResourceBundleControlProvider service.

Here is sample library structure.

The challenge here that:
The JavaDoc for ServiceLoader.loadInstalled() also states that providers on the application's class path are ignored.

In this case we need to specify java option -Djava.ext.dirs=lib with folder which contains java extensions.
