Set file retention of uploads in a chat

Purpose

The problem stems from a legal requirement, which means it needs to be addressed from the company's point of view rather than the end user's perspective.

Scope

This only applies to the Upload & Ask assistant or files that are directly uploaded in the chat. It does not include files ingested into the knowledge base.

Setting the retention

The retention time can only be set via Environment variables of the Chat microservice. This means it requires a deployment of the solution in order to activate it.

Where 0 means infinite.
Else the number is in days.
