IMPALA-2459: Implement next_day date/time UDF

Returns the date of the weekday that follows a particular date.
The weekday argument is a string literal indicating the day of the week.
Also this argument is case-insensitive. Available values are:
"Sunday"/"SUN", "Monday"/"MON", "Tuesday"/"TUE",
"Wednesday"/"WED", "Thursday"/"THU", "Friday"/"FRI", "Saturday"/"SAT".
For example, the first Saturday after Wednesday, 25 December 2013
is on 28 December 2013.
select next_day('2013-12-25','Saturday') returns '2013-12-28 00:00:00'
select next_day(to_timestamp('08-1987-21', 'MM-yyyy-dd'), 'FRIDAY')
returns '1987-08-28 00:00:00'
