func new hangs - improve logging

Description

cli func hangs when creating a new python function following the official guide

Steps to reproduce

Follow instruction here: https://learn.microsoft.com/en-us/azure/azure-functions/create-first-function-cli-python?tabs=linux%2Cbash%2Cazure-cli%2Cbrowser

python -m venv .venv
source .venv/bin/activate
func init --python
func new --name HttpExample --template "HTTP trigger" --authlevel "anonymous"

Nothing happens after func new, hangs for a long time (at least 5~10 minutes) and finally prints:

One or more errors occurred. (A task was canceled.)

That's all, nothing to help debugging

I tried your repro steps and it worked fine for me. I am on windows.

(.venv) C:\pythonrepro>func new --name HttpExample --template "HTTP trigger" --authlevel "anonymous"
Appending to C:\pythonrepro\function_app.py
The function "HttpExample" was created successfully from the "HTTP trigger" template.

(.venv) C:\pythonrepro>func start
Found Python version 3.9.13 (py).

Can you retry and see if it helps? And are you only getting that single line as error, nothing else?

@surgupta-msft I think it's environment related. Might even be just a temporary network problem.

But the biggest problem here is not the issue itself, it's that there is no message to debug the issue. May I suggest that you add better debugging information in case of an error rather than finding what caused the issue in my specific case, otherwise it will just be a wild goose chase
