time partitioning

Should time_partioning option come from template_table?

I consider time_partition is a part of the table. Therefore, time_partiioning should be inherited from template table.

It seems no option to get time partitioning info. A workaround could get field name and flag through INFORMATION_SCHEMA.TABLE_OPTIONS It's unclear to get expiration ms.

partition_expiration_days provides days for expiration

The expiration time cannot be configured through GUI, which requires CLI or API call.

For the first step, I will implement same API of jruby version.
