Link Applicant to Files in S3

This is Part 2 to adding files to an applicant's profile. Please refer to File Upload to S3 for Part 1.

🚧
"Key" Clarification
Not to be confused by S3's Object 'Key', the key refers to Fountain's identifier for the file you're uploading. In the Product, this is known as "Data Key". The S3 Object Key is passed in as s3_key.

We recommend using the same key for similar files you're collecting from applicants to prevent the creation of duplicate data keys. Example, if all your applicants have a resume, upload all the resume files as resume_file.
