    Add encryption support for volumes to libvirt
    
    Add support to encrypt Cinder volumes. Hooks within the libvirt
    driver encrypt volumes during the attach call. Created a
    VolumeEncryptor interface as well as several concrete subclasses
    (e.g., CryptsetupEncryptor and LuksEncryptor) to handle encryption.
    
    This feature depends upon related changes that have been accepted
    into Cinder (e.g., storing encryption key UUIDs for encrypted
    volumes).
    
    Implements: blueprint encrypt-cinder-volumes
