Review comment:
```suggestion
vars = [list(i) for i in airflov_context_vars.items()]
self.log.info("Exporting the following env vars:\n" +
"%s=%s\n" * len(vars), *sum(vars, []))
```
What do you think? In this way we will fix one pylint error (not caught yet
because this file is still in todo) :)
(the `sum(vars, [])` is a fastest flat map in python)
