Adding master fails due to missing SAN cert host

[holmesb]

Adding master nodes fails because the SAN cert lacks items for the new nodes.

"Unable to connect to the server: x509: certificate is valid for kubernetes, kubernetes.default, kubernetes.default.svc, kubernetes.default.svc.cluster.local, localhost, master-1, ..., not master-2"

The SAN cert should be updated with the new master to allow this to work. Currently this must be done manually.
