Review Comment:
seems ripe for abstracting entirely within a conversion function
[I mean L95-L96]

> Emit GaaSObservabilityEvent
> ---------------------------
>
> Key: GOBBLIN-1764
> URL: https://issues.apache.org/jira/browse/GOBBLIN-1764
> Project: Apache Gobblin
> Issue Type: New Feature
> Components: gobblin-service
> Reporter: William Lo
> Assignee: Abhishek Tiwari
> Priority: Major
> Time Spent: 1h 40m
> Remaining Estimate: 0h
>
> GaaSObservabilityEvents are a new events that provides a job summary from
> pipelines in GaaS. It differs from GobblinTrackingEvents as it runs once per
> job pipeline, and it intended to be easily queryable and alert on.
> We want to emit this observability event from GaaS by deriving it from a
> job's job status. Since this feature is Experimental and WIP, it is not
> expected to fill out all of the fields immediately.
