Logger and metrics in c++ code

[lucafuji]

Is your feature request related to a problem? Please describe.
Right now inside c++ code we don't have any logging or metric reporting. However, this is very useful. e.g. report gridDim, blockDim, etc.

Describe the solution you'd like
One thing we can try is to provide a golang call back to c call

Describe alternatives you've considered
Or reimplement the logic in c++
