[issue43717] Confusing OSError on HTTP CONNECT failure

[Michael Osipov]

New submission from Michael Osipov <1983-01-06 at gmx.net>:

When working with proxies and HTTP CONNECT I came across these lines: https://github.com/python/cpython/blob/63c69440c7adb0de1d191a8d3d100b335d5c2f81/Lib/http/client.py#L901-L903

I truly fail to see why this is an OSError. OSErrors (https://docs.python.org/3/library/exceptions.html#os-exceptions) describe a low-level issues, but HTTP is a high level protocol. I would expect something like NotConnected or at least something which derives from HTTPException.

OSError is expected on socket issues only.
