Allow the user to pass custom cert validity period with ClusterConfiguration.CertificateValidityPeriod and CACertificateValidityPeriod. The defaults remain 1 year for regular cert and 10 years for CA. Show warnings if the provided values are more than the defaults. Additional changes: - In "certs show-expiration" use HumanDuration() to print more detailed durations instead of ShortHumanDuration(). - Add a new kubeadm util GetStartTime() which can be used to consistently get a UTC time for tasks like writing certs and unit tests. - Update unit tests to validate the new customizable NotAfter.
