Puppet resource for managing an Etcd cluster

 Puppet lets you centrally manage every important aspect of your system using a
 cross-platform specification language that manages all the separate elements
 normally aggregated in different files, like users, cron jobs, and hosts,
 along with obviously discrete elements like packages, services, and files.
 .
 This Puppet module provides all what's needed to setup an Etcd cluster,
 including resources like etcd keys and such.
