bug: Cloudwatch parsing tests

[pnadolny13]

Related to #108. There are some minor data quality issues that require us to comment out some schema tests.

• IP address hashes are not parsed for some logs, I suspect due to truncation, but we get it in another message body so we should attempt to parse using the X-Forwarded-For list. Need to figure out what the other one is.
• status codes, request_path, and latency are missing for ~600 requests. Its an extremely small number relatively but it looks like those logs exist in data dog so it must be a bug with replication that they dont exist in Snowflake.
