Fixes #3062 There's no user-visible change in this PR. It carefully separates generated secrets (e.g. certs) from source secrets from the config (e.g. CAs), so that certs are generated on config changes which actually affect cert input. And same way separates etcd and Kubernetes PKI, so if etcd CA got changed, only etcd certs will be regenerated. This should have noticeable impact with RSA-based PKI as it reduces number of times PKI gets generated. Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
