support git subfolder

[finswimmer]

This PR contains necessary changes to poetry_core for implementing the possibility to add subfolders of a git repository as dependency.

This was original implemented in python-poetry/poetry#1822.

Merging this PR requires merging of python-poetry/poetry#2242 in poetry as well.

Implements: python-poetry/poetry#755

Is there any indication when this will make it into a (pre)release? I've got a pipenv project that takes over 15 minutes to lock dependencies that it's pulling from GitHub, and some basic testing suggests poetry should be a lot faster, but until I can install from subfolders we're out of luck...

Hello @dancmeyers,

unfortunately I think this feature has to wait for poetry version 1.2.

Supporting git subfolders is the missing piece of the puzzle for several repos I work on. I'd love to see this PR merged, @finswimmer is there anything I could do to help? - or is the poetry 1.2 requirement dependent on upstream tasks?

I'm closing this PR and the related in python-poetry/poetry#2242 for the following reasons:

• poetry's code base has changed a lot. I guess it would be easier to start from scratch then trying to adopt the current implementation
• I'm not aware of any PEP that says how to describe a git dependency located in a subfolder
