Option to always create src folder when using poetry new command

[Heus-Sueh]

Issue Kind

Brand new capability

Description

The Problem

Some people always prefer the app to be in the project's src folder instead of the project root and they always have to write poetry new with the --src option, which ends up wasting a millisecond, which seems little, but by putting this together you are wasting a lot of the user/developer's time

The Solution

An option in poetry's config.toml to always create the src folder

like this
use-src-dir = true

Impact

The impact will be positive in my opinion, because you don't adopt this project model and leave an option for those who want the other way, that way no one gets upset

Workarounds

you achieve this manually

and then if someone has set this configuration, how would they create a project that does not use the src layout? Yet another flag?

I expect that the millisecond saved is not going to be worth the trouble of worrying about such things, and this should be: thanks but no thanks
