debugging missing build information is hard

[willkg]

It's difficult to debug missing build information. There are multiple places where a failure results in the build information being missing from the frontend:

1. failure in receiving the SQS message
2. failure in reading the message or pulling the file from S3
3. failure in adding the build information to Postgres
4. failure in indexing into Elasticsearch

We should have easy-to-use tools to surface problems in any of these places given an S3 key or archive.mozilla.org url.

Also, it's not clear where build information came from. Was the build information captured through ingestion? Was it migrated from another source? Was it added by backfill? Fixing issue #545 might alleviate that--I don't know what that page was supposed to show.
