Notes:

• This is an example of how a hiera config file might look with an mock ldap backend. The backend in question still needs to be found or written.
• mapping from a DN to directory structure would be nice, so we would rather have to write: ou=virtual machines/ou=services instead to be compatible with the already existing yaml/json backends or something different entirely
• this needs to take into consideration that puppet expects keys to be defined in a way to enable implicit parameter injection in parameterized classes
• existing ldap backends for hiera: [1], [2]
• we should probably aim at integrating this in hiera-2 with regards to ARM-8 and the already imlemented ARM-9
• I'm not convinced that we should not just grab all this data from the stoney_core:_REST_API and use that as an integration point for puppet.
