reserveGameServerIds字段在创建gss时不生效

[shensl]

使用以下yaml创建gss不能实现创建预期编号为[1-4]的gs，最终gs与pod编号仍为[0-3]

apiVersion: game.kruise.io/v1alpha1
kind: GameServerSet
metadata:
  name: minecraft
spec:
  replicas: 4
  reserveGameServerIds: [0]
  gameServerTemplate:
    spec:
      containers:
        - name: minecraft
          image: registry.cn-hangzhou.aliyuncs.com/acs/minecraft-demo:1.12.2

查看events发现编号为4的pod被删除
