    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.
    
    Implements: blueprint encrypt-cinder-volumes
