Add Tableau endpoints for all api endpoints

[biblicabeebli]

Relatively easy with one moderate lift:

• Need to determine how to make WDC ... declaration? Work.
• Build a test that makes sure the endopnt's WDC's stated schema matches a generic output schema.
• need to test with @hydawo whether we Need that schema declaration is required or optional / what side effects it has.
  • what happens if there is an incorrect schema
  • can the schema be sparse/missing stuff
  • do we need keys or can we force lists because we have the schema? (can only do that if schema is fully enforced and static)
• I do not have tableau functional and had problems acquiring it. No linux, have to use mac (as of a year+ ago)
• DON'T do a special tableau=true parameter for determining credential type, do separate endpoints, even though it is more annoying. We don't wan't anyone using the endpoint to silently fail due to a hard-to-document-well hidden parameter.
