[SPARK-4861][SQL] Refactory command in spark sql
Follow up for #3712.
This PR finally remove ```CommandStrategy``` and make all commands follow
```RunnableCommand``` so they can go with ```case r: RunnableCommand =>
ExecutedCommand(r) :: Nil```.
One exception is the ```DescribeCommand``` of hive, which is a special case
and need to distinguish hive table and temporary table, so still keep
```HiveCommandStrategy``` here.
