    Add bug checks into format operation methods (#774818)
    
    Ensure pre-condition of never being passed a Partition object containing
    an open LUKS encryption mapping is met for format operation related
    methods.
    
    Bug 774818 - Implement LUKS read-write actions NOT requiring a
                 passphrase
