--upload-protocol for s3

[TrevorBenson]

I'm interested in extending the functions for --upload-protocol such that collector and report would both have available:

              {{module}}_grp.add_argument("--upload-protocol", default='auto',
                                 choices=['auto', 'https', 'ftp', 'sftp', 's3'],

Would an s3 protocol upload option be a welcome addition? If so I will create a branch and a draft PR for further discussion.

Thanks

Absolutely. I'm not sure if our current upload credentials are sufficient for s3 (just username/password at the moment), but if you have a use case for end users uploading to s3 then by all means feel free to open a PR.

Great.

I believe--upload-user & --upload-pass could be used as the AWS access and secret key of the s3 protocol, but I will review to see if I overlooked some constraints which would otherwise prevent it.

Many of the other --upload-[...] arguments I believe should easily map between protocols. The region would be a new argument and possibly a bucket, but I need to review --upload-url as given https as a protocol it may be flexible enough to handle both virtual host and path style s3 requests.
