Add support to export backup to s3 compatible storage

[remyleone]

Is your feature request related to a problem? Please describe.

I would like to backup my volumes to a s3 compatible storage solution

Describe the solution you'd like

I would like to put my credentials in a configuration file, the extensions would configure itself to send the backup to a s3 compatible storage (not necessary on aws, it could be a minio for instance)

Describe alternatives you've considered

Upload with SSH but it is not always practical as server got a limited amount of resources
