Bug 30373: Rewrite authorities_normal_unimarc to YAML

YAML version of authorities_normal_unimarc + sample auth types
Includes

This files works like it's marc21 counterpart:
* Defines an authority default framework
* Creates sample auth types by copy

Auth type codes and select fields/subfields are based on
french files in fr-FR install directory.

To test:
1. Apply this patch
2. Repeat UNIMARC install procedure as previous patches
3. Verify authorities_normal_unimarc.yml is loaded without problem
4. In the staff interface verify all auth types are present
