Serval Build Log

[johnml1135]

Option 1 - build log

Add it to the Build repo structure add a field called ExecutionLogs, but don't expose on the build endpoint.

• Severity, timestamp and string
• A new endpoint to grab the data (build/{id}/logs)
• Info on the steps and then they occurred
• Warn things link USFM errors, no prestranslations

Option 2 - serval log

Or we could create Engine logs - that keep growing for every step of the build and endpoint call. We could (A) shoehorn it into Loki or (B) make a new collection with the "last 200 messages" per engine.

Option 3 - just add more to EngineData

Or, we can add warning fields to ExecutionData such as
"Warning:type of warning": "here is a description of what happened"
