Goal

The goal is to delete user and log them out of the Cloud when account is deleted in Blender ID.

Part of https://developer.blender.org/T82969

How it works

If non-null date_deletion_requested is received by the user-modified webhook handler, the handler

• soft-deletes user record, sets email and names to nulls in it;
• deletes all session tokens.

Dependencies

The log out part depends on https://developer.blender.org/D10138 to work properly.
