    Switch to metadata.json for Puppet forge releases

    Since puppet 3.x, Puppet Labs Forge accept only the metadata.json file
    for module description (Modulefile is now deprecated).

    This patch :
     - convert the Modulefile to metadata.json.
     - bump major version to 5 (for juno), and deps.
     - switch to stackforge namespace.
     - relax pe version_requirement to 3.x.

    engine: configure deferred authentication method

    The default deferred_auth_method of password is deprecated as of
    Icehouse, so although it is still the default, deployers are strongly
    encouraged to move to using deferred_auth_method=trusts, which is
    planned to become the default for Juno.

    * It avoids storing user credentials in the heat database
    * It removes the need to provide a password as well as a token on stack create
    * It limits the actions the heat service user can perform on a users behalf.

    This patch aims to:
    * Set deferred_auth_method = trusts in /etc/heat/heat.conf for engine
    * Specify the roles to be delegated to the heat service user
       (trusts_delegated_roles in heat.conf, defaults to heat_stack_owner
       which will be referred to in the following instructions. You may wish
       to modify this list of roles to suit your local RBAC policies)
    * Create the role(s) in Keystone (optional and enabled by default).
