Dapr currently has a performance test that details the added latency for the Dapr sidecar. This test has the user app invoke Dapr over HTTP.

This issue is to add the same test only with the app invoking Dapr via gRPC.

Research direction
The existing HTTP performance test is likely in a file like tests/perf/... The contributor should examine that test and create a similar one using gRPC client to invoke Dapr sidecar. The Dapr gRPC client libraries are in the pkg/grpc directory. The test should measure latency for service invocation via gRPC and compare to HTTP baseline. Check existing performance test framework and documentation.
