Restoring from private azure devops feeds is flaky

See original GitHub issue

We have been seeing multiple issues when restoring from azure devops private feeds.

These errors usually manifest in 401/403/404 errors when attempting to restore packages, and are caused by a mix of bugs in NuGet / The credential provider / MSBuild.

While we have some more information as to when the issues will be fixed, the azure artifacts team recommended a wokaround:

Clear the nuget http-cache before attempting to restore any packages from these feeds
Set the following environment variables:" NUGET_PLUGIN_HANDSHAKE_TIMEOUT_IN_SECONDS=20 NUGET_PLUGIN_REQUEST_TIMEOUT_IN_SECONDS=20

The NuGet changes will be available in the 3.1.200 SDK, we should update Arcade (and dependent repos) to that version when it’s released to see if that solves the flakiness.

I think this might just been an agent network problem, looking at the logs for that failed build leg, I see stuff such as:

Which means it had problems restoring from even the sleet feeds, and not just with the artifacts feeds.
