Allow an option to exempt groupfolders from user quota #4239
Description
Currently Group Folders are included in user quotas. Why is it necessary to allow to exclude them?
Imagine a situation where a company has a group folder with shared projects. These projects can be really large. But as they are company projects, they do not belong to a particular user, and users should not be "charged" with participating in these projects. If they do, quotas does not have any sense, as more they participate in company projects, less they can keep on their private drives. Quotas should only be counted on their private drives, allowing limiting usage of uncontrolled and invisible space.
