API Project: File Metadata Microservice for freeCodeCamp

User stories:

1. I can submit a form that includes a file upload.
2. The from file input field has the "name" attribute set to "upfile". We rely on this in testing.
3. When I submit something, I will receive the file name and size in bytes within the JSON response

Usage :

• Go to https://battle-canvas.glitch.me, and upload a file using the provided form.
