Bug: Incorrect data types for sourceIPAddress and sequencer Fields in S3RecordSchema Model

[leandrodamascena]

Expected Behavior

When working with S3 LifecycleTransition events, the value of the sourceIPAddress field is s3.amazonaws.com instead of an IPv4 value. Additionally, the sequencer field is only populated on PUT and delete object events.

Current Behavior

These fields are using incorrect data types.
