Add new type: netapp_quota

This is an attempt for a new type to manage quotas.

Example:

    netapp_quota { "/vol/vol01/qtree01":
      ensure    => present,
      type      => tree,
      volume    => 'vol01',
      disklimit => '10G'
    }

Disclaimer: I've not actually run this type against a real NetApp (yet), meaning this type has been developed purely against the available api documentation and some api responses I've captured beforehand.

Hope I'll be able to test the code against a real machine this week.
