    Parse algorithm from cipher for ephemeral disk encryption

    Nova's keymgr implementation used to have default values
    for the algorithm and bit length. Castellan does not have
    default values, and when Castellan replaced keymgr in
    Ib563b0ea4b8b4bc1833bf52bf49a68546c384996, the parameters
    to the create_key method were not updated. This change
    parses the algorithm from the cipher value and passes it
    to Castellan's key manager interface.
