The AWS session and s3 manager are concurrent safe, they should be reused whenever possible:
See https://pkg.go.dev/github.com/aws/aws-sdk-go/aws/session
Currently, an aws session and s3 client/manager are created every time a call to Upload, CurrentID or Download is made. I changed it so it creates one session and S3 manager during app startup and reuse it afterwards.
