Interceptors for Python, Node and other languages

[Malayks]

Hello, I have been extensively using the GO-gRPC interceptor to trace few microservices written in go and using gRPC but I have a need to create a py and node service and was wondering if we have any interceptors for python and Javascript so that my polyglot environment is fully traced.

If not I would like to know how can I write my own. Any reference or documentation which can help me write the interceptors for py and js similar to the ones we have fro go and java

@Malayks we would very much value the contributions. Last time I checked, the GRPC-python API did not support interceptors natively, and that was the blocker there. I did not check Javascript.

Could you take a look at the GRPC APIs and report back here? I can apply some gentle pressure to the GRPC-team if the APIs are not sufficient to do the actual interception... they really should be! Thanks.

@bensigelman I took a quick look and could not find native support for interceptors in Node GRPC APIs, did not investigate Python as Node is a priority for me.

@Malayks I added something to the tail of grpc/grpc#8767 (comment) ... feel free to weigh in if you feel like it :)

Thanks @bensigelman. Looks like for the time being, writing a wrapper is the only option.
