Create all routes for Ingredient

[TomNgTech]

Schema for Ingredient (create 1 ingredient) = { id, name, measurementType }

As a dev, I would like to have the routes for ingredients so that I can create, get, modify/update, delete the ingredients.

AC:

• [x] Have a GET all ingredients route
• [x] Have a GET ingredient by id
• [x] Have a PUT ingredient
• [x] Have a POST ingredient by id
• [x] Have a DELETE ingredient by id
• [x] Include 404, 500 and 200 HTTP Status Codes
