backup: cannot configure OVH S3 object storage as destination repo

[nrauso]

NS8 does not allow to configure the OVH S3 object storage as backup repo.

Steps to reproduce

• Create new bucket on OVH S3 object storage
• Try to connect it to NS8 as new backup repo

Expected behavior

The new repo should be available and reachable

Actual behavior

The repo adding procedure generates an error:

[
  {
    "field": "parameters",
    "parameter": "parameters",
    "value": "2024/05/29 09:52:16 Failed to size: AuthorizationHeaderMalformed: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'sbg'\n\tstatus code: 400, request id: tx787f64f6cea340d2826ed-006656fad0, host id: tx787f64f6cea340d2826ed-006656fad0\n",
    "error": "backup_repository_not_accessible"
  }
]

In plain text:

2024/05/29 09:52:16 Failed to size: AuthorizationHeaderMalformed: The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'sbg'
        status code: 400, request id: tx787f64f6cea340d2826ed-006656fad0, host id: tx787f64f6cea340d2826ed-006656fad0

The issue seems related to the lack of mandatory additional attributes needed by rclone.

This issue may also impact other S3 object storage providers.
Here's what happens with Wasabi:

[
  {
    "error":"backup_repository_not_accessible",
    "field":"parameters",
    "parameter":"parameters",
    "value":"2024/09/30 09:33:02 Failed to size: AuthorizationHeaderMalformed: The authorization header is malformed; the region 's3.eu-central-2.wasabisys.com' is wrong; expecting 'us-east-1'\n\tstatus code: 400, request id: RGCX0TXQRXB2B95X, host id: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX=\n"
  }
]

In testing: core 3.0.0-dev.1

[nrauso]

test case: VERIFIED

I am now able to properly manage multiple S3 object storage repositories for backups.
Restoring applications works as expected as well.
