Make repository services configurable

[lolautruche]

Some eZ repository services are designed to allow settings injection:

• UserService
• RoleService
• NameSchemaService
• URLAliasService

However there is currently no way to define these settings, except for a few (e.g. anonymous user ID).

It would be nice to expose some semantic configuration for this:

ez_core_extra:
    system:
        default:
            repository:
                user:
                    default_placement: 12
                    content_type_id: 4
                    group_id: 3
                    password_hash_type: ~
                    site_name: ez.no
                name_schema:
                    limit: 150
                    sequence: ...
                url_alias:
                    show_all_translations: false

Sounds like a core feature, something we should prioritize now.

But if in core I would maybe not tie them to much to the internal settings structure of repo code, as:

• It might change, but the concepts they represent probably won't
• some of the settings involved are typically used several places (e.g. show all translations could be higher level like the legacy setting which is system wide to show all translations)
