Add Direct Lookups for LC Medium of Performance Thesaurus for Music

[sfolsom]

Create direct lookups for the following LC Medium of Performance Thesaurus for Music

The Samvera QA Code seems to offer search for some LC vocabs: https://github.com/samvera/questioning_authority/wiki/Connecting-to-Library-of-Congress-%28LOC%29.

• Hopefully we can turn this on for our app and add new vocabs.
• If not, we’ve discussed the possibility of converting LC suggest2 json response into linked data that QA can recognize and use the linked data module to translate

Related links: See https://id.loc.gov/techcenter/searching.html for API documentation.

Example of a direct search config to base new config off: https://github.com/cul-it/qa_server/blob/f3083a8f1392e72890f8d6e6a763c9e0ace1ea0c/config/authorities/linked_data/oclcfast_direct.json#L32

Data to bring in and translate, if available in the API: https://docs.google.com/spreadsheets/d/1rPvEoP9iYNkxJ0eWC8gXe3ci7e6mhW0da59xkGhadi0/edit#gid=239265704

@sfolsom This is ready for you to test on lookup-int! Direct lookup results use the id.loc.gov api (same results as what you'd find here: https://id.loc.gov/search/?q=cs:http://id.loc.gov/authorities/performanceMediums). Each result has an id, label, and uri parsed from: https://id.loc.gov/search/?q=cs:http://id.loc.gov/authorities/performanceMediums&format=json

Please let me know if you'd like any changes!

Example endpoint: https://lookup-int.ld4l.org/authorities/search/loc/performanceMediums?q=goblet

Looks good. Another authority where variant labels are also searchable.
