Add configurable catalog zone naming

- New setting 'catalog_zone_name' (default: 'catz') to change the name of
  the per-view catalog zone. Full DNS names (multiple labels) are
  supported; names are handled as dns.name.Name objects, making the
  comparison case-insensitive and tolerant of trailing dots.
- New setting 'catalog_zone_name_includes_view' (default: False). When
  enabled, the catalog zone name is prefixed with the view name:
  '<view>.<catalog_zone_name>'.
- The transfer endpoint now serves exactly the one configured catalog
  zone name per view instead of accepting both 'catz' and
  '<view>.catz'.
- The catalog zone NOTIFY now targets only the configured name instead
  of notifying for both variants. Scheduling moved to
  catalog_zone_manager, which owns all catalog zone naming.
