Dapr 1.7.2

Fixes panic due to nil pointer dereference in API Logging

Problem

When enabling the API logging preview feature, a nil reference can occur and crash the sidecar. In addition, the logged API for gRPC is being fixed not to include a memory address but just the method's name.

Root cause

Logic for API logging in gRPC did not initialize logger object for internal service to service communication for Dapr sidecar.See #4544.

Solution

Skip logging for internal gRPC invocation and print method name only for other gRPC API calls.
