Subject: Fix etcd cert generation when etcd_interface is defined

- Refactor certificate generation to properly accept overrides of etcd_interface
  per host and set the certificate SANS and peer URLs properly.

- Add sanity checking to user-set values of etcd_interface to provide a better
  error message
