repository source should support a file system link to a index file like pip's --index-url for usage without a web server

Feature Request

I somehow understand the discussions and reluctance here and here about pip's find-links and why it will not be added, even if this would be very useful for company repositories which don't want to maintain a webserver.

But pip --index-url allows to pass a local html file, like file:///c:/wheelhouse/simple/index.html or c:\wheelhouse\simple\index.html.

Tools like piprepo create a index.html file with links to the local file system.
This might not be as convenient as 'find-links', but it serves the same purpose.

Poetry's source could be able to deal with these these local files (Simple API Repository and Single Page Link Source).
A source could use the attribute path separate the use cases.

Examples for usage:

[[tool.poetry.source]]
name = "foo"
path = "file:///C:/wheelhouse/simple/index.html"

[[tool.poetry.source]]
name = "foo"
url = "C:\wheelhouse\simple\index.html"

[[tool.poetry.source]]
name = "foo"
url = "file:///C:/wheelhouse/simple/index.html"

find-links feature request duplicates #5983 please close

[harrandt]

This feature is explicitly not about find-links but rather index-url. There is no need to iterate a directory or guess around, you get the explicit links to the packages.

[dimbleby]

hmm, well there's existing discussion of this feature in #5983, not sure it was worth splitting

either way I don't suppose it's likely to happen unless you want to step up with a merge request.

stackoverflow suggests that it might not be so hard, suggest experimenting with something along those lines if this is something you want to see
