A new config param protocol is added to the otlpConfig for the otlp exporter. It defaults to http but it can also take the grpc value to enable basic (insecure) gRPC exporting in the agent. For the agent tests, multiple changes were needed:
Added the @grpc/grpc-js and @grpc/proto-loader packages needed to implement a basic gRPC server.
Add the actual OTLP protobuf files needed to configure the gRPC server.
Create a OTLPGRPCServer with the same interface as the current OTLPServer.
