Localization configuration preset

[vkublytskyi]

Some local markets expect that Magento will be configured in some particular way. To simplify locale-specific configuration Magento 2 may introduce some configuration presets.

User scenario:

1. Admin change a locale
2. System shows him actual and recommended a configuration for selected locale.
3. Admin able to modify nothing/all/only some configuration options at once

@HirokazuNishi No good references for now. It may be a useful feature so I placed this epic with the lowest priority to investigate how important it is and what exactly we should implement.
