(This is not user-facing, but rather internal use of the kubeconfig in the tests/inside the machine). This was added 4 years ago as a workaround, but instead of a global timeout we should rather use contexts with timeouts/deadlines (and we do!). Setting a global timeout breaks streaming Kubernetes pod logs. Signed-off-by: Andrey Smirnov <andrey.smirnov@siderolabs.com>
