Refactor Catalog API

[mikekistler]

The Catalog API should be refactored to comply with standard HTTP/REST conventions. Specifically:

• The PUT operation to update a catalog item should take the item id in the path
• The GET operations on
  • /api/catalog/items/by/{name}
  • /api/catalog/items/type/{typeId}/brand/{brandId}
  • /api/catalog/items/type/all/brand/{brandId}
• should be dropped and replaced with optional query parameters name, type, and brand on the GET on /api/catalog/items
• The "text" parameter of GET on /api/catalog/items/withsemanticrelevance/{text} should be changed from a path parameter to a query parameter

I've started work on this but want to get the OpenAPI support (#631, #632) merged in ahead of it.
