authority - specific value API #534

Source

#406

Summary

I need some fairly deep data to make authority links in /guid/ pages. (Currently pulled through direct queries.) I could get this through the existing Authority API, but I think a new API which accepts eg

node=record attribute, type=sex, value=female

and returns enough information to make the green links work eg

• https://test.arctos.database.museum/info/ctDocumentation.cfm?table=ctattribute_type#sex
• https://test.arctos.database.museum/info/ctDocumentation.cfm?table=ctsex_cde#female

would be worthwhile for two reasons

1. accessibility, this should be easy and readily support roll-your-own GUID pages, and
2. cost, this should be as computationally simple as possible, and have a very long cache refresh interval
