Add S3 storage as option for Domino backup and restore

The new Domino backup and restore in v12 is really great and works very well.

Domino alreay supports storage of Daos files to AWS S3 buckets via the Tier 2 storage.

It should also be possible to use S3 buckets for backup and restore, to avoid third party solutions on top of Domino for this.

    The S3 integration has been published:

    This integration provides a flexible solution, where you are in full control.

    There will be a S3 command line based integration soon published here https://github.com/HCL-TECH-SOFTWARE/domino-backup

    I am currently testing it and the performance is not great.

    In addition you will net a lot of storage for full backups every night.

    This would only help if you are using your own S3 storage where compression and de-duplication is enabled.

    The S3 integration configuration use the AWS CLI S3 command-line and the Minio client. From the use cases it does not make sense to have the same tighter integration into backup/restore like DAOS T2, because it would add complexity to the backup/restore application.

    S3 integration might be useful for backup delta files and also transaction logs which are written only once.

    It might be even a good candidate for DAOS backup (which is not part of Domino backup -- which takes care about databases and templates + translog like any other application backup agents).

    But S3 is not the ideal storage for Domino backup data.

    I have looked into it and did a lot of tests. And there are much more efficient solutions. Still Domino backup will support S3 as a back-end using the command-line integration also described in the GitHub repository.

    I first also thought S3 would be a good candidate for backup, but looking into the details showed it is not a very efficient approach.
