Quota control at Nova APIGW for VM's metadata and injected files. These controls work on the API side directly, no need to gather the usage from the bottom pod. The quota management and control in Tricircle is described in the design doc: https://docs.google.com/document/d/18kZZ1snMOCD9IQvUKI5NVDzSASpw-QKj7l2zNqMEd3g/ BP: https://blueprints.launchpad.net/tricircle/+spec/implement-stateless Change-Id: Ib3f0a908118df4a9eb98d9bf56ebd9be48ebde10 Signed-off-by: Chaoyi Huang <joehuang@huawei.com>
