       Use the specified algorithm (e.g. SHA256_RSA4096) and the key to AVB-sign
       the specified image. Otherwise it uses the existing values in info dict.

       Specify any additional args that are needed to AVB-sign the image
       (e.g. "--signing_helper /path/to/helper"). The args will be appended to
       the existing ones in info dict.
