Can we inject the default queue?

maybe reject it in the first version; we can refer to how prioirtyCass for such kind of default value.

How about the default weight in admission hook
|
|
||
| type QueueSpec struct { | ||
| // The weight of queue to share the resources with each other. | ||
| Weight int32 `json:"weight,omitempty" protobuf:"bytes,1,opt,name=weight"` |

What's the meaning of the value? Should have a clear desc.

| * Proportion plugin: | ||

| Proportion plugin is used to share resource between `Queue`s by weight. The deserved resource of a queue is `(weight/total-weight) * total-resource`. When allocating resources, it will not allocate resource more than its deserved resources. |

IIUC, it seems total-weight will sum up all the weight of the queues, as the queue increases, the (weight/total-weight) will change. How do scheduler adjust the proportion of resources an old queue occupies ? Let's say the queue resources are all used up, will this trigger a preemt?

Another case, cluster resources may also change

Kube-batch will continue executing those actions every X period.
