This change removes JodaCompatibleZonedDateTime and replaces it with ZonedDateTime for use in
scripting.
Breaking changes:
* JodaCompatibleDateTime no longer exists and cannot be cast to in Painless. Use ZonedDateTime
instead.
* The dayOfWeek method on ZonedDateTime returns the DayOfWeek enum instead of an int from
JodaCompatibleDateTime. dayOfWeekEnum still exists on ZonedDateTime as an augmentation to
support the transition to ZonedDateTime, but is now deprecated in favor of dayOfWeek on
ZonedDateTime.
