Wave 04: Read, Update, Delete

RESTful Endpoints: Read, Update, and Delete

Create the following endpoints, with similar functionality presented in the Hello Books API:

As a client, I want to send a request...

...to get one existing planet, so that I can see the id, name, description, and other data of the planet.
... with valid planet data to update one existing planet and get a success response, so that I know the API updated the planet data.
... to delete one existing planet and get a success response, so that I know the API deleted the planet data..
- Each of the above endpoints should respond with a 404 for non-existing planets and a 400 for invalid planet_id.
