Use a friendly file name when downloading files (e.g. support package)

[labo-flg]

Use case

When a file is generated by the platform, most of the time we use a generated UUID for the file name.
This is the case for the support packages, or the exclusion lists for instance.

When the user download these files, a direct link is generated to the storage, and thus the filename is preserved : it's an unfriendly UUID.
We have all the required context to improve this and use a meaningful name, such as the support package date-time, or the exclusion list name.

Current Workaround

No workaround

Proposed Solution

Proper solution would be to introduce a new API downloadSupportPackage for instance that will build the right file specs and push it for download.
