BDP-25893: OH table PARTITIONED BY DATE

[HotSushi]

Summary

Before this PR, OH didn't support following SQL:

spark.sql("CREATE TABLE db.table (data string) PARTITIONED BY (datefield DATE)").show()

After this PR, it does.

Details

OH server achieves this by considering DATE as a clustering column, just like string (say with value "2025-01-01").

There was a design choice to consider DATE as a timestamp column, but it would require major redesign on our REST TimeSpec APIs. Considering as a clustering column, doesn't miss-out on any optimization strategies.
