upload file via GraphQL with multipart requests.

the graphql queries and mutations are as follows - 

```graphql

type Query {

  author(id: Int!): Person!

}

type Mutation {

  coverPhoto(file: Upload!): Int!

}

```

the mutation accepts file and returns back the length in bytes.

The data stored in the app is in-memory and is **not** recommended for production.

To run the mutation, you can use Postman or directly use this cURL command at the root of the project (it has a sample image)

```bash

curl --location --request POST 'http://localhost:8080/graphql' \

--form 'operations="{\"query\": \"mutation updateProfilePhoto($file: Upload!) {  coverPhoto(file: $file)} \", \"variables\": {\"file\": null}}"' \

--form 'map="{\"0\": [\"variables.file\"]}"' \

--form '0=@"./assets/grand-palais-mrsauravsahu.jpg"'

```

this will return the length of the file in bytes.

If you import this request in Postman, make sure the file path is correct. 👍
