S3 Support

[Tiziano Bacocco]

Hi, to everyone, i'm interested in native S3 support on proxmox, is anyone
working on it ( to avoid double work )?
Second question, my idea is to reuse existing pbs code but upload chunks
and index to s3, sounds good? The thing puzzling me is that a lot of code
will end up duplicated , when actually only the part uploading to S3
instead of pbs would be different, chunking, fleeching, restoring, backup,
qemu interface would be almost identical
