Add dynamic adjust disk qos support
Currently, OpenStack has support set the disk's QoS when creating Instance or attaching volume to instance. The related blueprints is [1] and [2].
However, we have no method to dynamic adjust the disk's QoS during the instance is running or without detaching the volume.
The implementation of [1] and [2] is based on libvirt driver's capability, and libvirt driver has already support online-tune the disk's QoS. We can add this feature to libvirt driver.
