[jira] [Created] (RATIS-478) Support custom grpc interceptors

Elek, Marton created RATIS-478:
----------------------------------

             Summary: Support custom grpc interceptors
                 Key: RATIS-478
                 URL: https://issues.apache.org/jira/browse/RATIS-478
             Project: Ratis
          Issue Type: Improvement
            Reporter: Elek, Marton
            Assignee: Elek, Marton


While Ratis already has opencencus dependencies the current Ozone tries to use opentracing. (See HDDS-1017). 

To support opentracing (or any other tracing utility) we need an extension point to add any grpc server/client interceptor. With the interceptor it would be possible to propagate existing tracing context over the wire.

This patch is a very small modification: if the classname is the interceptor is defined, the interceptor will be added to the client/server side.
