    Add encryption support for volumes
    
    Add support to encrypt Cinder volumes. Modified the libvirt driver to encrypt
    volumes during the attach call. Created a new VolumeEncryptor class that is
    responsible for encrypting volumes. The default implementation does not do
    enryption, and a DmCryptVolumeEncryptor is provided to encrypt volumes using
    dmcrypt.
    
    This feature requires related changes within Cinder (e.g., storing encryption
    key UUIDs for encrypted volumes), which have not yet been accepted. This patch
    is fully functional but is will require further modifications (that are
    relatively minor) once the related Cinder changes have been accepted.
