Enhanced gRPC call logging

- Write calls to file, one file for each channel
- Log started, inbound msg, outbound msg, and closed events, for each RPC
- Distinguish between different RPCs by assigning an ID to each one

Also, removed redundant DeviceId attribute from GrpcChannelId, as all
channel IDs were already created using a client key that contains the
DeviceID. It seems a better approach to not restrict the definition of a
channel ID and have that defined simply as a string.
