    Add ephemeral storage encryption for LVM back-end images
    
    This patch adds ephemeral storage encryption for LVM back-end instances.
    Encryption is implemented by passing all data written to and read from
    the logical volumes through a dm-crypt layer. Most instance operations
    such as pause/continue, suspend/resume, reboot, etc. are supported.
    Snapshots are also supported but are not encrypted at present.
    
    The proposed code provides data-at-rest security for all ephemeral
    storage drives, preventing access to data while an instance is
    shut down, or in case the compute host is shut down while an instance is
    running.
    
    Options controlling the encryption state, cipher and key size are
    specified in the "ephemeral_storage_encryption" options group. The boolean
    "enabled" option turn encryption on and off and the "cipher" and "key_size"
    options specify the cipher and key size, respectively.
    
    Note: depends on cryptsetup being installed.
    
    Implements: blueprint encrypt-ephemeral-storage
