OKR O6.KR1

As a part of our latency SLO work for realtime feed, we need to log events that are exceeding p999 latency. This will allow us to monitor and create alert in future.

To do

• Add an env variable to structured-data : LatencyThreshold
• In structured-data handlers, before events are published to the topics, check event_published - event_created. If this is > p999, log it along with event.identifier

QA (Acceptance criteria)
Able to see few logs in cloudwatch of the above type.
