MDCT-1993 api updates

[gmrabian]

Description

MDCT-1993 modify api to match standards

1. Fetch to a specific item returns a 404 when the response is empty (instead of 200)
2. Create calls return a 201 instead of 200
3. Fetch’s with full primary keys will convert to a get from a query
4. An update where the matching record does not exist returns a 404 (instead of a 500)

How to test

Try out the mcr postman collection from confluence! Check that:

• Create now returns a 201 instead of 200
• Update without existing item returns 404
• Update without new data returns 400
• Fetch where specific item doesn't exist returns 404 (does not apply to queries like "reportsByState")
