Description

We noticed an increased in machines getting "command not found" errors from azure-cli version 2.84.

It appears machines are struggling to load modules within the 60 second thread timeout, and are not loading the command table correctly and getting "command not found" errors. Retry logic on machines means command table cannot be loaded if it hits the timeout, and continues on to hit a "command not found" error.

Default module timeout increased to 120.

We add core.module_load_timeout az config parameter to manually control the timeout threshold.

Also add telemetry field ThreadTimeout to track the issue.

The git hooks are available for azure-cli and azure-cli-extensions repos. They could help you run required checks before creating the PR.

Please sync the latest code with latest dev branch (for azure-cli) or main branch (for azure-cli-extensions).
After that please run the following commands to enable git hooks:

pip install azdev --upgrade
azdev setup -c <your azure-cli repo path> -r <your azure-cli-extensions repo path>
