s3_handler doesn't handle delete events

Read steps/handlers/s3_handler.py, starting with handle and _extract_data, and inspect how the S3 event data identifies delete events or delete markers before get_object is called. Done means S3 delete notifications can be forwarded without attempting to retrieve the deleted object or raising NoSuchKey.

Expected Behavior

I want to forward logs from s3 delete event
s3_handler._extract_data shouldn't try to retreive an object if it has delete marker or even is of type delete

Actual Behavior

following method in s3_handler fails as it tries to access deleted object.
def _extract_data(self):
s3_client = self._get_s3_client()
response = s3_client.get_object(
Bucket=self.data_store.bucket, Key=self.data_store.key
)
body = response.get("Body")
self.data_store.data = body.read()

Steps to Reproduce the Problem

1. Set up s3 bucket notification to trigger templated lambda upon object delete
