@puckpuck @jpkrohling please look at this PR.

@Kimbohlovette This also includes the changes from your checkoutservice PR. The changes to the productcatalog files look fine, but we would want the changes to be contained to a single service.

I spoke with @Kimbohlovette today and mentioned that this is not supported yet as OTel logs in Go are still in development.
He will reach out to the OTel Go team to check if he can help out on bringing this to Stable.

Closing this PR for now.
