    Copy encryptors from Nova to os-brick

    Currently, when creating an encrypted volume from an image, Cinder
    writes raw data to the encrypted volume. When Cinder uploads an
    encrypted volume to an image, it writes encrypted data to the image.
    As a result, Nova cannot use these images or volumes.
    To fix above problem, cinder needs to add encryptor attach/detach
    layers.
    As both Nova and Cinder needs to use the module, the fix is to
    move it to os-brick.
    It copies encryptors from Nova to os-brick, and keep all interfaces
    unchanged except initialization.
