## What changes were proposed in this pull request?
Set createTime for every hive partition created in Spark SQL, which could be used to manage data lifecycle in Hive warehouse. We found that almost every partition modified by spark sql has not been set createTime.
```
mysql> select * from partitions where create_time=0 limit 1\G;
*************************** 1. row ***************************
PART_ID: 1028584
CREATE_TIME: 0
LAST_ACCESS_TIME: 1502203611
PART_NAME: date=20170130
SD_ID: 1543605
TBL_ID: 211605
LINK_TARGET_ID: NULL
1 row in set (0.27 sec)
```
