Description
Describe the request
Add an option to skip network requests when using arduino board list or at least an option to set a timeout when estabilishing an HTTP connection (--http-connect-timeout option similar to --discovery-timeout?)
Describe the current behavior
Running arduino board list on a system that has network access but no internet (without a proxy) results in the process being stuck during the Querying builder API for board identification... step for 260 seconds:
$ rm .arduino15/inventory.yaml ; time arduino-cli board list --json --log --log-level trace
...

To work around this I'm currently forcing builder.arduino.cc to 127.0.0.1 in /etc/hosts:

Arduino CLI version
arduino-cli Version: nightly-20241128 Commit: 6cd084b Date: 2024-11-28T01:35:05Z
Operating system
Linux
Operating system version
Ubuntu 20.04.6 LTS
Additional context
I'm preparing a Linux installation image with preconfigured arduino-cli that will be used on PCs without access to the internet, so every time a new, unrecognized board is connected, the board list command takes a long time.
Issue checklist
- I searched for previous requests in the issue tracker
