INTERVAL ... HOUR TO SECOND syntax
URL: https://github.com/apache/spark/pull/24472#issuecomment-496358371
 
 
   Hi, @gatorsmile and @cloud-fan .
   
   Could you give us some directional advice, please?
   - First, this PR wants to support `INTERVAL ... HOUR TO SECOND` like 
`INTERVAL ... DAY TO SECOND` like Presto/Terradata. It looks reasonable to me, 
too.
   - Second, originally, this PR added a new pattern and new function (which is 
similar to the existing one). To avoid maintaining two similar functions, I 
recommended to extend the existing pattern and handling `DAY` and `HOUR` with 
the same function. To sum up, we will support 2~4 additionally.
   1. SELECT INTERVAL '0 23:59:59.155' DAY TO SECOND (Current Spark)
   1. SELECT INTERVAL '23:59:59.155' HOUR TO SECOND
   1. SELECT INTERVAL '23:59:59.155' DAY TO SECOND
   1. SELECT INTERVAL '1 23:59:59.155' HOUR TO SECOND
   
   If you think these are okay, I want to merge this PR. How do you think about 
this?
