Instances can be launched more than the reserved amount

[Hiroaki Kobayashi]

For instance reservation, Blazar assumes that create server requests which use reserved resources must has server group ID in their scheduler hint parameter. However, users can forget to specify the server group ID. In this case, instances can be created more than the reserved amount because Blazar depends on ServerGroupAntiAffinity filter for limiting resource usage. Blazar have to deny such a server create request.
