Implement Soft-Delete for SCL-Files

[david-monichi]

User Story

As an user

I want to be able to delete files

So that they are not visible via standard API but can be searched trough with an additional endpoint.

Acceptance criteria

• Soft-Delete functionality must be disabled by default for an installation so that a system behaves as before without any additional changes.
• The existing endpoints do behave as before even when soft-delete is enabled, which means that when the feature Soft-Delete is enabled files can't be accessed via existing endpoints and the system will return a 404 in such cases.
• With an additional added search endpoint it's possible to search trough all SCD-Files (soft-delete or not soft-deleted), soft-deleted files will be marked as deleted
• the backend will detect already deleted files and versions. Which means that a version can't be redistributed twice when a SCD-File has been soft-deleted und re-uploaded again. The system is aware of all previous versions and will handle versions conflicts over a given resource identified by there id.

@david-monichi-bp can you check @pascalwilbrink pull request to see if it matches this ticket?

Hi, for sure this are required changes but this feature we implemented for TransnetBW is going little bit further. Would it be ok to add us as developers and we bring our solution to a feature branch so that we can discuss about concrete changes via PR?

Sounds like a plan! I will add you
