Review comment:
There are two reasons blocking us to do that:
1. Modules dynamically added to "sys.path" is not possible to get via
`pkg_resources.get_distribution`
2. If `grpcio-tools` is not present in the Python environment and is
installed via this script, we can make sure that the version is correct.
Does that make sense?
