Disable forwarding proto stream by default in node_grpc_main.cc (#1013) 

...and use `LoadStateFromFile` from `MapBuilderStub`. The `LoadState` stub
that's used in `Node::LoadState` streams the state file instead, which can now
be used by explicitly setting the `--upload_load_state_file` flag.

Solves problems with the gRPC message size limit when loading large state files.
