    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 requires further
    modifications (that are relatively minor) once the related Cinder
    changes have been accepted.
