Comment 10 for bug 1519537

I don't believe we should expose that kind of data thru API. First, because it may expose some internal data, and also because it's just overkill. I agree we need more debug info, and services should allow to provide it, but pushing it thru RPC and API is not needed. Instead, we should adopt oslo.reports library in our services and allow core plugins/drivers/services to extend the output (it's already supported by oslo.reports).
