NFS backup driver

[Marc Methot]

Hardcoded values prevent use of nfs as a cinder backup driver

https://github.com/openstack/tripleo-heat-templates/blob/master/puppet/services/cinder-backup.yaml#L12
  CinderBackupBackend:
    default: swift
    description: The short name of the Cinder Backup backend to use.
    type: string
    constraints:
- allowed_values: ['swift', 'ceph']

This forces to use less intuitive methods of configuring it and made me think twice as to why it wasn't an allowed value.
puppet-cinder already has everything we need to configure NFS so no changes needed there.

Reason: we have gate problems again, please do not restore or recheck, I'll take care of this one when gate is back stable.
