Change show_chunks/drop_chunks using creation time

- Updated show_chunks, drop_chunks APIs to get the affected
chunks using chunk creation time metadata based on the
"date/time/interval" like boundary specified for the INTEGER
columns.

- We honor "integer_now" function if it's specified so as to keep
backwards compatibility with the existing behavior
