Integrate AWS s3/Any other cloud bucket storage

[Presto412]

Currently, the files uploaded are stored on the webserver. It would help if an abstraction is created that can implement different types of storage buckets, such as AWS s3/Google Cloud Storage etc.

Would you be providing the credentials for the bucket?

@PhilzAce1 sure

@uzair-ashraf Once a PR is raised, I'll test it locally with my own creds, so if you want to test, you may have to use your own. Although if you need to test at any point you can just upload your code to the branch and I shall test locally.
