Exported Meltano usage stats, aggregated per plugin

If a user has opted in to usage tracking, Meltano captures anonymized metrics on elt and invoke. Can we add this as a per-plugin metric within SingerHub?

Those metrics appear to be tracking in Google Analytics, as per this code snippet:

• https://gitlab.com/meltano/meltano/blob/master/src/meltano/cli/elt.py#L141

It would be helpful also to capture 'success/fail' indicator, but even without that, this would still be a big help during the SingerHub discovery process.

One challenge might be in securely extracting this data and landing in a way which can be consumed by SingerHub.
