Write documentation on how to make a custom logging.yml in your project

[antonymilne]

Once logging.yml has been removed, we need to add to the docs how a user can create a custom logging.yml in their project conf. This should include one or more nice copy and pasteable examples that demonstrate things a user might actually want to change in their logging (e.g. change the logging level maybe?).

Note the incremental option discussed on https://docs.python.org/3/library/logging.config.html. Would be nice to show how that can be used to simply edit the logging config rather than needing to overwrite the whole file. See https://github.com/kedro-org/kedro/pull/1491/files#diff-3434028fb098b270c88bc7a0689c0e4bc358442e8f29672ddb6bf87c11a0e28f for an example of how this works. Ask me to explain...

Makes sense to be done after #1469.

So much like the project CLI being removed from the template I'm fine with this living docs.

However what do we think about a kedro template {thing} command?

We could use it to create templates for custom CLI, logging, datasets etc. a bit like we do for kedro pipeline create.

Thoughts?

I think it could help but I feel it is something that falls into the "nice to have" category. Although looking at the statistics seems people do use kedro pipeline create? Maybe I am wrong here.

I just found that the cli.py is also outdated, maybe another sign that not many people are actually using it.

kedro pipeline create is the best way to create pipelines, the idea above is very much a 'nice to have'.

cli.py is a funny one as I think we've made it quite hard to change, I'm not sure it's super well documented how you create your own. Like I would expect to see it here, but it's not there.

It's actually here. Actually, I am only able to search it with the keywords cli.py, I suspect a normal user will struggle to find this information.

I am not sure how many projects will need the cli.py for a project base usage, plugins are probably the way to go for cross-projects.
