 Type to manage the rabbitmq erlang cookie securely
 
 This is essentially a private type used by the rabbitmq::config class
 to manage the erlang cookie. It replaces the rabbitmq_erlang_cookie fact
 from earlier versions of this module. It manages the content of the cookie
 usually located at "${rabbitmq_home}/.erlang.cookie", which includes
 stopping the rabbitmq service and wiping out the database at
 "${rabbitmq_home}/mnesia" if the user agrees to it. We don't recommend using
 this type directly.
