Typehints for python grpc-methods

I added typehints using the mypy-protobuf package.

This requries that `mypy-protobuf` python package is installed.

I created a `requirements-dev.txt`-file and added it to the
docker-container. The bindings can now be regenerated as follows.

Do `make docker-shell`.

Inside the newly opened shell you can enter

```
make libs/gl-client-py/Makefile pygrpc
```

and

```
make libs/gl-testing/Makefile testgrpc
```
