Postman tests for api exercises

I created a postman script that tested the endpoints of the api-express-database exercise.

In order to get the script setup:

• Save the JSON to your machine
• Import the file inside postman
• Open the collection

The process to use this was as follows:

• Clone the students repository
• Copy an .env. file containing a postgres URL
• Start the server
• Run the postman collection

I think it would be nice to have test suites like these for each of the exercises that have endpoints we can test, this will save a lot of time "guessing" if the endpoints work based off of the handler code.

A small note with that particular test suite. When I originally wrote it, the optional filters for GET /books and GET /pets were core criteria, however, now they are extension criteria.
