HYC-1997 - Affiliation Updates

[bbpennel]

https://unclibrary.atlassian.net/browse/HYC-1997

• Added and adjusted department vocabulary
  • Fixed incorrect comma delimiters in term fields
• All solr fields will not store the id for affiliations, both in affiliation_label_tesim and in person objects.
  • Facet filtering by affiliation is by id now, rather than by display form
  • Affiliation values get looked up in the vocab and translated to short_labels before display, in facets and work pages
• If a department is part of a hierarchy (so it has multiple semi-colon delimited sections in the term field), then the affiliation_label_tesim field will now have an entry for each step of the hierarchy, rather than just the final step before.
  • This means that "School of Medicine" and other top level affiliations will be listed for specific subdepartments, and can be used to find everything by the "School of Medicine".
• Removed conditional logic to deal person objects not having "index:" fields, since they should all have that now (search prod affirmed this)
