[Feature Request] Remove duplicated code from /examples

Motivation

Hi, this is a small suggestion to refactor the code in the examples directory.

The reason for it is that different examples have a lot of code in common (see here, here and here for the examples). I guess this small change would increase the readability

Solution

I would suggest to create a utils.py file inside the examples dir and put the duplicated code here. For instance, for the logging example described above we could simply create get_logger(cfg: "DictConfig") function and import it inside examples if needed

Alternatives

Do nothing and close this issue :)

Additional context

If it seems as an OK improvement I would be able to create a PR and address this issue. Please let me know what you think!
