Kylin UI: Enable partition date column to support date and hour as separate columns

[Delu Zhu]

Hi Kylin Developers,

I'm working on migrating our hourly cube building pipeline to Kylin, and from 
your official docs Task KYLIN-1427 has been included in the release note of 
apache/kylin to enable partition date column to support date and hour as 
separate columns.
This is a good new, but after upgrading to kylin 1.5, I found this feature has 
not been enabled on Kylin UI yet.
So when will KYLIN-1441 ( the corresponding changes at ui side) be released?

ThanksDelu
