[SPARK-2919] [SQL] Basic support for analyze command in HiveQl

The command we will support is
```
ANALYZE TABLE tablename COMPUTE STATISTICS noscan
```
Other cases shown in https://cwiki.apache.org/confluence/display/Hive/StatsDev#StatsDev-ExistingTables will still be treated as Hive native commands.
