pkg/errors is archived and while there is go-errors/errors as an alternative, it lacks wraping methods. kubeadm has specific neends and it's better to implement something minimal locally instead of introducing another depedency. - Implement basic wrapped errors and stack trace support. cmd/kubeadm/app/util/errors. - Remove unused error codes >1. At some point it seems we broke these and 1 was returned for all error types. - Remove the Error type in preflight and separate the printing of '[preflight]' message and the error return from preflight checks. - Print an 'error:' prefix for all errors.
