I am not really familiar with grpc.aio. Welcome any MR to get it started.

Thanks for reporting. What if you just create one `PromClientInterceptor()` and use that instance to intercept the channel?

What I am suggesting is make a single instance of "PromClientInterceptor", then you can used it in multiple clients. .e.g. ` PROM_CLIENT_INTERCEPTOR = PromClientInterceptor()) a = grpc.intercept_channel(PROM_CLIENT_INTERCEPTOR) b = grpc.intercept_channel(PROM_CLIENT_INTERCEPTOR)...
