KYLIN-4312 Specified cube when querying by API

[hit-lacus]

This is backend part, check https://issues.apache.org/jira/browse/KYLIN-4312.

After frontend part finsihed, should be look like this.

[hit-lacus]

需求背景

1. 数据缺失
   比如A这个人 她想查abcf四个维度 ，B这个人她想查bcd这三个维度，指标都一样。但是A是在 1月3号建了Cube，B是在8号建的Cube。
   这时候我查bc这两个维度的时候就会命中B的cube ，那前面的时间就没有了

2. 满足测试
   测试时无法测试特定的Cube，只能频繁地Enable Disable Cube

测试

1. 为两个设置相同的Cube 分别构建Segment，但是Segment Range不同

2. WebUI 查询

命中SimpleCube_02

3. 强制切换Cube，使之命中 SimpleCube_01
