Comment 3 for bug 1863298

After some discussion, we have agreed to use the following approach to fix the bug:

While managing a share, even if there are no available quotas the operation will be completed by allowing the quotas to be exceeded, and the service will log a warning. Since the quotas are going to be exceeded, some other operations that also need to allocate resources are going to be blocked by the OverQuota error, so the administrator will need to adjust the quotas to make this operations work again.
