NIFI-1420 Fixing minor bugs in GetSplunk
- Adding a Time Zone property so the Managed time ranges use the provided time zone when formatting the date strings - Adding a Time Field Strategy property to choose between searching event time or index time - Making the next iteration use previousLastTime + 1 ms to avoid overlap - Fixing bug where GetSplunk incorrectly cleared state on a restart of NiFi - This closes #299
