[pbs-devel] [PATCH proxmox-backup] api: return s3 client errors during datastore create with context

[Christian Ebner]

The error context might contain information directly pointing to the
reason why the bucket cannot be reached during the datastore creation
bucket access check.

For example, the following text will be shown to the user in the error
dialog:
```
failed to access bucket: client error (Connect): error connecting to https://test.s3.pve-c1.local:7480/
- dns error: failed to lookup address information: Name or service not known (400)
```
