added heritage validation before delete and added 2 additional test events.

At a high-level the following changes were made:

1. Changed version to 0.3.0
2. created a new def process_delete_record function to combine "repeating" tasks between A, PTR, and CNAME process. The code was combined with what was there before. Instead of doing the same process over 3 times, I just created a function and call it 3 times.
3. The def process_delete_record function performs:

• 4. checks TXT heritage validation (do I own it? does the instance ID match?)
• 5. Also sends SNS notification if heritage validation fails.
• 6. If not not pass validation, it skips deletion and sns notify
• 7. If so, it deletes the records - (A, PTR, or CNAME and associated TXT)

8. Fixed LOGGER.info lines that had a typo (missing parameter) in the sns notification caller. Example line 2274 but several others.
9. Fixed lOGGER.info to convert MAX_API_RETRY to string when writing to log. Example line 2264 but several others.
10. Updated new_get_resource_record with several fixes.

• 11. Return "" instead of Non if not found -- better align with parent function that calls it.
• 12. Checks the value of the list_resource_record_sets to match what should be returned. This is because the list_resource_record_sets API returns the next record (instead of matching exact) so wrong record can be retrieved if we do not check it.
• 13. MaxItem value changed to string.

14. Fixed def parse_heritage to add more logging and better input validation
15. Fixed def get_heritage_item to check input type and add more logging.
