Inspection Mechanism For Capacity Limited Host

Registered by wangxiyuan on 2016-04-21

Cinder has a scheduler filter called "CapacityFilter" which allow users to create volume under capacity limit. But some APIs which don't go through cinder-scheduler will break the destination host's capacity . Such as extend volume, create volume from snapshot, copy volume and so on.
So IMO, we need add an inspection mechanism for this APIs to ensure that these actions should not break the destination host's capacity.
This bp will introduce a check function at API layer and the APIs which may break the capacity will be checked before send the requset to cinder-volume.
