While investigating a large number of errors in highlighting I noticed the vast majority where canceled. This commit adds special handling for it and in the process does a few other things to the observability here: - Log duration in these errors. This is useful signal to understand if a slow request is being canceled, or we have bad debouncing in a client. - Re-use the tracers logger. This has many more fields and avoids duplication. - Downgrade cancel error to warning. - Include error problem in logs. - Factor out the snippet log field creation. Note I didn't include snippet in the cancel log since it's unlikely to be related to the code being highlighted. Easy to add in if we find that is incorrect. Test Plan: CI will exercise this code path. Otherwise I will follow-up on dotcom. (cherry picked from commit b89b99c)
