I punted on this in bug 1442306, but we should validate the resulting file against the JSON schema.

The schema is embedded in initialization.yml in the buildhub repository: https://github.com/mozilla-services/buildhub/blob/master/jobs/buildhub/initialization.yml#L71-L198 I punted on this mostly because we don't currently have a json schema Python module vendored in m-c, but it's not hard to fix that.

We have two copies of voluptuous in tree, surely that ought to count for something.

For what it's worth, we already use jsonschema to validate perfherder blobs before we log them. Surely we can reuse that? https://searchfox.org/mozilla-central/search?q=jsonschema&case=false&regexp=false&path=py
