Brad Davidson 45d8c1a1a2 Soft-fail on node password verification if the secret cannot be created
Allows nodes to join the cluster during a webhook outage. This also
enhances auditability by creating Kubernetes events for the deferred
verification.

Brad Davidson 239021e759 Consistently use constant-time comparison of password hashes
As per https://github.com/golang/go/issues/47001 even subtle.ConstantTimeCompare should never be used with variable-length inputs, as it will return 0 if the lengths do not match. Switch to consistently using constant-time comparisons of hashes for password checks to avoid any possible side-channel leaks that could be combined with other vectors to discover password lengths.

Brad Davidson 215fb157ff Add `certificate rotate-ca` to write updated CA certs to datastore
This command must be run on a server while the service is running. After this command completes, all the servers in the cluster should be restarted to load the new CA files.

Brad Davidson 3d01ca1309 Make supervisor errors parsable by Kubernetes client libs
This gives nicer errors from Kubernetes components during startup, and
reduces LOC a bit by using the upstream responsewriters module instead
of writing the headers and body by hand.

Brad Davidson 38706eeec0 Defer ensuring node passwords on etcd-only nodes during initial cluster bootstrap
This allows secondary etcd nodes to bootstrap the kubelet before an
apiserver joins the cluster. Rancher waits for all the etcd nodes to
come up before adding the control-plane nodes, so this needs to be
handled properly.
