Inject identifier to gRPC Client

[jwulf]

At the moment, gRPC Client logs don't identify the task type of the worker, or if it is the gRPC Client for a ZBClient. In projects with multiple workers, they do not provide information about which parts are failing.

For example:

endpoint     | {"id":"gRPC Channel","level":50,"message":"GRPC ERROR: 14 UNAVAILABLE: GOAWAY received","pollMode":"Long Poll","taskType":"gRPC Channel","time":"2019 Oct-26 10:44:19AM","timestamp":"2019-10-26T10:44:19.354Z"}
endpoint     | {"id":"gRPC Channel","level":50,"message":"GRPC Channel State: IDLE","pollMode":"Long Poll","taskType":"gRPC Channel","time":"2019 Oct-26 10:44:19AM","timestamp":"2019-10-26T10:44:19.354Z"}
endpoint     | {"id":"gRPC Channel","level":30,"message":"gRPC Channel reconnected","pollMode":"Long Poll","taskType":"gRPC Channel","time":"2019 Oct-26 10:44:19AM","timestamp":"2019-10-26T10:44:19.355Z"}

The GRPCClient class should take an id string that is Worker: ${taskType} or ZBClient to add in debugging.
