move ignore preflight checks from flag to kubeadm configurations

[pacoxu]

refer to kubernetes/kubernetes#129401

After we add SystemVerification check in upgrade, we need to skip in some kinder testing.

This PR follows the suggestions kubernetes/kubernetes#129401 (review) to move flags to configurations.

• don't pass the --ignore-preflight errors as flags for commands.
• pass them via config in the big config that has all the config 'kinds'.
