IMPALA-12856: Event processor should ignore processing partition
with empty partition values

While processing partition related events, Event Processor (EP) is
facing IllegalStateException if the partition fetched from HMS has
empty partition values. Even though this is a bug in HMS which returns
partitions with empty values, EP should ignore such partitions instead
of throwing IllegalStateException.

Note: Added a debug option 'mock_empty_partition_values' to add
malformed partition objects.

Testing:
- Manually verified the test provided in jira details in local env.
- Added unit test to return empty partition values and verify EP state.
